Item 1.01 Entry into a Material Definitive Agreement.

On October 6, 2026, Charlton

Aria Acquisition Corporation, a Cayman Islands exempted company (the “Company”), entered into a Business Combination

Agreement (the “Business Combination Agreement”) with KQC Quantum, Inc., a Delaware corporation (“Parent”),

KQC MS Limited, a Cayman Islands exempted company and a wholly owned subsidiary of Parent (“Merger Sub”), and, for

the limited purposes specified therein, Korea Quantum Computing Co., Ltd., a corporation organized under the laws of the Republic of Korea

(“KQC Korea”) and ST Sponsor II Limited, a Cayman Islands exempted company (the “Sponsor”).

Business Combination Agreement

Structure of the Business

Combination

Prior to the execution of

the Business Combination Agreement, the shareholders of KQC Korea transferred all of the issued and outstanding shares of KQC Korea to

Parent in exchange for shares of common stock of Parent (the “Reorganization”), with the result that Parent is the

direct legal and beneficial owner of 100% of the issued and outstanding shares of KQC Korea. The Business Combination Agreement provides

that the Reorganization is complete and that no further step in respect of KQC Korea is required in order to consummate the transactions

contemplated by the Business Combination Agreement (the “Transactions”).

Immediately prior to, and

conditioned upon the occurrence of, the Effective Time (as defined below), Parent will effect a share subdivision, share split, reverse

share split, share dividend or other recapitalization of its common stock (the “Pre-Closing Recapitalization”) such

that (i) a sufficient number of shares of Parent common stock is authorized but unissued to permit Parent to issue the shares issuable

pursuant to the Business Combination Agreement, the shares reserved under the equity incentive plan to be adopted by Parent (the “Equity

Incentive Plan”) and the Earnout Shares (as defined below), and (ii) the quotient of the Equity Value divided by the Fully Diluted

Parent Stock (each as defined below) is equal to the Reference Price (as defined below). The Pre-Closing Recapitalization will be effected

pro rata and will not alter the relative percentage interests among the existing holders of Parent common stock.

At the closing of the Transactions

(the “Closing”), and in accordance with sections 232 to 239 of the Companies Act (As Revised) of the Cayman Islands

(the “Cayman Companies Act”), Merger Sub will merge with and into the Company (the “Merger”), with

the Company surviving the Merger as a direct wholly owned subsidiary of Parent (the time at which the Merger becomes effective, the “Effective

Time”). Parent has agreed to apply, in its own name, for the initial listing on The Nasdaq Stock Market LLC (“Nasdaq”)

of the shares of its Class A common stock, par value $0.0001 per share (“Parent Class A Common Stock”), to be issued

pursuant to the Business Combination Agreement. The parties intend that, upon the Effective Time, Parent will be the successor issuer

to the Company for purposes of Rule 12g-3(a) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

Merger Consideration

At the Effective Time, by

virtue of the Merger: (i) each Class A ordinary share of the Company issued and outstanding immediately prior to the Effective Time (other

than shares validly redeemed and shares in respect of which dissenter rights have been validly exercised and not withdrawn or lost under

section 238 of the Cayman Companies Act) will be cancelled and converted into the right to receive the Per Share Merger Consideration

(as defined below); (ii) each Class B ordinary share of the Company (each, a “Founder Share”) issued and outstanding

immediately prior to the Effective Time will be cancelled and converted into the right to receive the Per Share Merger Consideration,

subject to any forfeiture, deferral or earn-back arrangements mutually agreed among the parties to the Business Combination Agreement;

(iii) each right of the Company outstanding immediately prior to the Effective Time (each, a “Right”) will cease to

represent a right to acquire Class A ordinary shares of the Company and will instead be cancelled and converted into a number of shares

of Parent Class A Common Stock equal to the Per Share Merger Consideration divided by eight; and (iv) each unit of the Company outstanding

immediately prior to the Effective Time that has not previously been separated will automatically be separated into its component Class

A ordinary share and Right, which will be treated as described in clauses (i) and (iii) above.

The “Per Share Merger

Consideration” is a number of shares of Parent Class A Common Stock equal to the quotient of (i) the Reference Price divided

by (ii) the quotient of the Equity Value divided by the Fully Diluted Parent Stock. The “Equity Value” is $80,000,000.

The “Reference Price” is the amount per Class A ordinary share of the Company that would be payable out of the Company’s

trust account (the “Trust Account”) on a redemption, calculated in accordance with the Company’s amended and

restated memorandum and articles of association (as amended) as of the date that is two business days prior to the date on which the proxy

statement/prospectus relating to the Transactions is first mailed to the Company’s shareholders, or such other date as Parent and

the Company may agree in writing. The “Fully Diluted Parent Stock” is the total number of shares of Parent common stock

issued and outstanding immediately prior to the Effective Time, including any shares issuable in respect of the Convertible Debt (as defined

below) or reserved under the Equity Incentive Plan, the continuing awards outstanding under the Equity Incentive Plan and the option grants

to be made at the Closing. Because the Pre-Closing Recapitalization is required to be effected such that the quotient of the Equity Value

divided by the Fully Diluted Parent Stock is equal to the Reference Price, the Per Share Merger Consideration is expected to be equal

to one share of Parent Class A Common Stock.

No fractional shares of Parent

Class A Common Stock will be issued in the Merger. In lieu thereof, each holder who would otherwise be entitled to a fractional share

will receive an amount in cash, without interest, equal to the product of the Reference Price and the fraction concerned, rounded to the

nearest whole cent.

Earnout

Following the Closing, the

holders of Parent common stock as of immediately prior to the Effective Time (the “Parent Legacy Holders”) will be

entitled to receive up to 1,500,000 additional shares of Parent common stock (the “Earnout Shares”), measured after

giving effect to the Pre-Closing Recapitalization, in three separate tranches of 500,000 shares each during the five years commencing

on the date of the Closing (the “Earnout Period”). A tranche is earned when the daily volume-weighted average trading

price of Parent Class A Common Stock equals or exceeds $12.50, $15.00 or $20.00, respectively, on any 20 trading days within any 30 consecutive

trading days entirely within the Earnout Period. Each tranche may be earned only once, and more than one tranche may be earned during

the same period. Upon a change of control of Parent during the Earnout Period, all Earnout Shares not previously issued will be deemed

earned and will be issued immediately prior to the consummation of such change of control.

Convertible Debt

KQC Korea has outstanding

convertible bonds and other convertible debt instruments (the “Convertible Debt”). Because KQC Korea is not a constituent

company in the Merger, the Convertible Debt will not be assumed by the surviving company by operation of the Merger. Prior to the Closing,

Parent has agreed to use, and to cause KQC Korea to use, reasonable best efforts to obtain from each holder of Convertible Debt a written

consent and amendment providing that KQC Korea will remain the obligor in respect of the Convertible Debt and that, upon conversion following

the Closing, the holder will receive shares of Parent Class A Common Stock in lieu of shares of KQC Korea.

Governance Following the

Closing

Effective as of the Effective

Time, the board of directors of Parent will consist of seven directors, comprising four directors designated by Parent and three directors

designated by the Company, together with the number of directors qualifying as “independent” within the meaning of the applicable

Nasdaq listing rules and SEC regulations required to satisfy Nasdaq’s initial and continued listing standards, one of whom will

be designated by the Company and three of whom will be designated by Parent. Parent will establish an audit committee, a compensation

committee and a nominating and corporate governance committee, each satisfying the applicable Nasdaq and SEC requirements.

Representations, Warranties

and Covenants

The Business Combination Agreement

contains customary representations, warranties and covenants of the parties. The representations and warranties do not survive the Closing,

and there are no post-Closing indemnification obligations under the Business Combination Agreement, in each case other than in respect

of fraud or wilful breach. The covenants include, among others, covenants relating to the conduct of the respective businesses of the

Company and of Parent and its subsidiaries prior to the Closing, the preparation and filing by Parent of a registration statement on Form

S-4 (the “Registration Statement”) that will include a proxy statement of the Company and a prospectus of Parent, the

Company’s pursuit of an extension of the deadline by which it must consummate an initial business combination, reciprocal exclusivity,

Parent’s efforts to satisfy Nasdaq’s initial listing requirements, the parties’ cooperation in seeking a private placement

financing and any backstop arrangement, and Parent’s responsibility for the costs and expenses of the Transactions, subject to a

cap of $2,500,000 and specified exceptions.

Parent has also agreed to

engage, and to cause KQC Korea to engage, an independent registered public accounting firm registered with the Public Company Accounting

Oversight Board (the “PCAOB”) and reasonably acceptable to the Company no later than 15 business days after the date

of the Business Combination Agreement, to convert the historical financial statements of Parent and its subsidiaries from Korean generally

accepted accounting principles to generally accepted accounting principles in the United States, and to deliver audited consolidated financial

statements for each period required by Regulation S-X to be included in the Registration Statement, audited in accordance with the standards

of the PCAOB, no later than November 30, 2026. Parent has further agreed to deliver such additional, updated or re-audited financial statements

as are necessary in order that the Registration Statement contains financial statements satisfying the age requirements of Regulation

S-X at the time the Registration Statement is declared effective including, if the Registration Statement has not been declared effective

on or before February 14, 2027, to deliver audited consolidated financial statements for the fiscal year ended December 31, 2026, audited

in accordance with the standards of the PCAOB.

The Business Combination Agreement

provides that, at any time prior to receipt of the approval of the Company’s shareholders, the board of directors of the Company

may, subject to specified notice and matching rights in favor of Parent, change its recommendation in respect of the Transactions or cause

the Company to terminate the Business Combination Agreement in order to enter into a definitive agreement with respect to a Superior Proposal

(as defined in the Business Combination Agreement), if the failure to take such action would be inconsistent with the fiduciary duties

of the board of directors of the Company under applicable law.

Conditions to Closing

The obligation of each party

to consummate the Transactions is subject to the satisfaction or waiver of customary conditions, including: the absence of any law or

order prohibiting the Transactions; receipt of the approval of the Company’s shareholders; the Registration Statement having been

declared effective under the Securities Act of 1933, as amended (the “Securities Act”), with no stop order in effect

or threatened; approval for listing on Nasdaq of the shares of Parent Class A Common Stock to be issued pursuant to the Business Combination

Agreement, subject only to official notice of issuance; approval of an extension of the deadline by which the Company must consummate

an initial business combination to a date not earlier than the date of the Closing; the expiration or termination of any applicable waiting

period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended; and the aggregate cash available at the Closing, including

funds remaining in the Trust Account after giving effect to all shareholder redemptions and the net proceeds of any private placement

financing, being not less than $30,000,000 or such other amount as the Company and Parent may agree in writing (the “Minimum

Net Cash Condition”).

The obligation of the Company

to consummate the Transactions is subject to additional conditions, including the accuracy of the representations and warranties of Parent

and Merger Sub and their performance of their covenants, delivery of the PCAOB-audited financial statements described above, the execution

and delivery of ancillary agreements, receipt of consents in respect of the Convertible Debt, receipt of other specified consents, approvals

and filings, Parent’s procurement of a directors’ and officers’ liability insurance “tail” policy, the filing

of Parent’s amended and restated certificate of incorporation, the adoption of the Equity Incentive Plan and the making of the option

grants contemplated at the Closing, Parent’s delivery of an independent valuation report addressing the fair market value of Parent

as of a date not more than 60 days prior to the date of the Closing, and the absence of a continuing Parent Material Adverse Effect (as

defined in the Business Combination Agreement). The obligation of Parent and Merger Sub to consummate the Transactions is subject to additional

conditions, including the accuracy of the Company’s representations and warranties and its performance of its covenants, the execution

and delivery of the ancillary agreements, the instruction of the trustee to release the funds in the Trust Account, the Company’s

receipt of an independent fairness opinion from a U.S.-credentialed financial adviser reasonably acceptable to Parent, and the absence

of a continuing SPAC Material Adverse Effect (as defined in the Business Combination Agreement).

Termination

The Business Combination Agreement

may be terminated at any time prior to the Closing in specified circumstances, including: by mutual written consent of Parent and the

Company; by either Parent or the Company if the Closing has not occurred on or before June 30, 2027, which date is automatically extended

for an additional 60 days if the Registration Statement has been filed with the SEC but has not yet been declared effective; by either

party if a governmental authority has issued a final and non-appealable order permanently prohibiting the Transactions; by either party

if the approval of the Company’s shareholders is not obtained at the meeting convened for that purpose; by either party if the extension

of the Company’s deadline to consummate an initial business combination is not approved, if that deadline passes without the Closing

having occurred, or if the Company becomes required to redeem its Class A ordinary shares and liquidate the Trust Account; by either party

upon an uncured breach by the other party; by either party if the Minimum Net Cash Condition is incapable of being satisfied as of the

date of the Closing; by the Company if the financial statements described above are not delivered by the applicable date specified in

the Business Combination Agreement; by the Company in order to enter into a definitive agreement providing for a Superior Proposal, subject

to compliance with the applicable notice and matching provisions; and by the Company if, during the 45-day period following the date of

the Business Combination Agreement, it discovers any fact, circumstance or condition relating to Parent and its subsidiaries that it reasonably

believes is material and adverse to them, individually or in the aggregate.

Upon a valid termination,

the Business Combination Agreement will become void without liability on the part of any party, except that no termination will relieve

any party of liability for fraud or wilful breach and except that specified provisions, including those relating to confidentiality, the

extension, the costs and expenses of the Transactions and the effect of termination, will survive in accordance with their terms.

Intended Tax Treatment

For United States federal

income tax purposes, the parties intend that the Merger, together with the Reorganization, will satisfy the requirements of Section 351

of the Internal Revenue Code of 1986, as amended.

The foregoing description

of the Business Combination Agreement is not complete and is qualified in its entirety by reference to the full text of the Business Combination

Agreement, a copy of which is filed as Exhibit 2.1 to this Current Report on Form 8-K and is incorporated herein by reference. The Business

Combination Agreement contains representations, warranties and covenants that the parties made to one another as of specific dates. The

assertions embodied in those representations, warranties and covenants were made solely for purposes of the Business Combination Agreement

and may be subject to important qualifications and limitations agreed by the parties in connection with negotiating its terms, including

qualification by disclosure schedules that are not filed publicly and that may apply contractual standards of materiality in a way that

differs from what may be viewed as material to shareholders. Accordingly, investors should not rely on the representations, warranties

and covenants, or any description of them, as characterizations of the actual state of facts or condition of any party or any of its affiliates.

Sponsor Support Agreement

Concurrently with the execution

of the Business Combination Agreement, the Company, Parent and the Sponsor entered into a Sponsor Support Agreement, dated October 6,

2026 (the “Sponsor Support Agreement”). The Sponsor holds 255,000 Class A ordinary shares of the Company underlying

the Company’s private placement units and 1,905,000 Founder Shares (collectively, the “Sponsor Shares”).

Pursuant to the Sponsor Support

Agreement, during the period from the date of the Sponsor Support Agreement until the earlier of the Closing and the valid termination

of the Business Combination Agreement, the Sponsor has agreed, for the benefit of Parent, to (i) cause all Sponsor Shares to be counted

as present at the meeting of the Company’s shareholders convened to approve the Transactions, including any adjournment or postponement

of that meeting, for purposes of calculating a quorum, (ii) vote all Sponsor Shares in favor of the proposals to be submitted to the Company’s

shareholders in connection with the Transactions, (iii) not redeem any Sponsor Shares, including in connection with that meeting or any

meeting convened to approve an extension of the deadline by which the Company must consummate an initial business combination, and (iv)

comply with the transfer restrictions set forth in the letter agreement, dated October 24, 2024, among the Company, the Sponsor and certain

officers and directors of the Company (the “Insider Letter”), subject to the exceptions set forth therein. Any permitted

transferee of Sponsor Shares must enter into a written agreement with Parent and the Company agreeing to be bound by the provisions of

the Sponsor Support Agreement and the Insider Letter.

The Company has agreed to

enforce the Insider Letter in accordance with its terms and not to amend, modify or waive any provision of the Insider Letter without

the prior written consent of Parent, which consent may not be unreasonably withheld, delayed or conditioned. The Sponsor Support Agreement

also contains customary representations and warranties of the Sponsor, including as to its ownership of the Sponsor Shares, and provides

that securities of the Company subsequently issued to, or acquired by, the Sponsor will be subject to its terms. The Sponsor Support Agreement

terminates on the earlier of the Closing and the valid termination of the Business Combination Agreement in accordance with its terms.

The foregoing description

of the Sponsor Support Agreement is not complete and is qualified in its entirety by reference to the full text of the Sponsor Support

Agreement, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.

Parent Support Agreement

In connection with the Business

Combination Agreement, on October 6, 2026, the Company, Parent and certain stockholders of Parent (the “Supporting Parent Stockholders”)

entered into a Parent Support Agreement (the “Parent Support Agreement”). The Supporting Parent Stockholders hold in

the aggregate 910,621 shares of Parent common stock (such shares, the “Subject Stock”).

Pursuant to the Parent Support

Agreement, during the period from the date of the Parent Support Agreement until the earlier of the Closing and the valid termination

of the Business Combination Agreement (the “Interim Period”), each Supporting Parent Stockholder has agreed, with respect

to all of its Subject Stock, to (i) be present, or be counted as present, for purposes of establishing a quorum at each meeting of Parent’s

stockholders at which such holder is entitled to vote, (ii) vote, or deliver a written consent, in favor of the adoption and approval

of the Pre-Closing Recapitalization, the Merger, the Business Combination Agreement, the ancillary agreements, any amendments to Parent’s

organizational documents and the other Transactions, (iii) vote against any acquisition proposal or other proposal for the acquisition

of Parent, any proposal that could reasonably be expected to delay or impair Parent’s ability to consummate the Transactions, and

any proposal in competition with or materially inconsistent with the Business Combination Agreement or the ancillary agreements, and (iv)

vote against any material change in Parent’s present capitalization, organizational documents, corporate structure or business other

than as contemplated by the Business Combination Agreement or the ancillary agreements. Any written consent requested by Parent must be

delivered within 24 hours of the request.

Each Supporting Parent Stockholder

has also agreed to execute and deliver related documentation and take other action in support of the Transactions as reasonably requested

by Parent or the Company, including stockholder written consents and applicable ancillary agreements, and the Parent Support Agreement

contemplates that certain of the Supporting Parent Stockholders will enter into a Lock-Up Agreement.

During the Interim Period,

each Supporting Parent Stockholder has agreed not to, without the Company’s prior written consent, transfer, pledge, encumber or

otherwise dispose of any Subject Stock, enter into any contract, option, derivative or hedging arrangement with respect to a transfer

of Subject Stock, grant any proxy or power of attorney with respect to the Subject Stock, permit any lien on the Subject Stock other than

specified permitted exceptions, deposit the Subject Stock in a voting trust or subject it to any voting arrangement other than a stockholders’

agreement effective only from and after the Closing, or take any action that would have the effect of adversely affecting the Supporting

Parent Stockholder’s ability to perform its obligations. Parent has agreed not to permit or effect any transfer of Subject Stock

in violation of the Parent Support Agreement.

Subject to and conditioned

upon, and effective as of, the Closing, each Supporting Parent Stockholder will release the Company, Parent and their respective past

and present directors, officers, employees, agents, predecessors, successors, assigns and subsidiaries from claims arising out of or relating

to such holder’s capacity as a current or former holder of equity securities of Parent in respect of acts, omissions, events or

circumstances occurring or existing at or prior to the Closing. The release excludes, among other things, claims arising under the Business

Combination Agreement, the Parent Support Agreement and the other ancillary agreements, rights to indemnification, exculpation, contribution,

reimbursement or advancement of expenses under Parent’s or KQC Korea’s organizational documents or any indemnity agreement,

rights under any directors’ and officers’ liability insurance or tail policy, and claims for compensation, expense reimbursement

or benefits or under any employment or similar agreement with any Group Company.

The foregoing description

of the Parent Support Agreement is not complete and is qualified in its entirety by reference to the full text of the Parent Support Agreement,

a copy of which is filed as Exhibit 10.2 to this Current Report on Form 8-K and is incorporated herein by reference.

Ancillary Agreements

At or prior to the Closing,

the Sponsor and each Parent Legacy Holder holding five percent or more of the outstanding shares of Parent common stock as of immediately

prior to the Effective Time will enter into a lock-up agreement with the Company and Parent (each, a “Lock-Up Agreement”),

in the form attached as an exhibit to the Business Combination Agreement. Pursuant to the Lock-Up Agreements, each such holder will agree

not to transfer the shares of Parent common stock issued, issuable or retained by such holder in connection with the Transactions, together

with any securities paid as dividends or distributions in respect of those shares or into which those shares are exchanged or converted

(such holder’s “Restricted Securities”), during the period commencing on the date of the Closing and ending on

the earliest of (x) the date that is six months after the Closing, (y) with respect to up to 50% of such holder’s Restricted Securities,

the date on which the closing price of the Parent Class A Common Stock equals or exceeds $12.50 per share (as adjusted for share splits,

share dividends, reorganizations and recapitalizations) for any 20 trading days within any 30 consecutive trading day period commencing

after the date of the Closing, and (z) the date on which Parent completes a liquidation, merger, share exchange, reorganization or other

similar transaction that results in all holders of Parent common stock having the right to exchange their shares for cash, securities

or other property.

The Business Combination Agreement

further contemplates that, at the Closing, Parent, the Sponsor and certain Parent Legacy Holders will enter into a registration rights

agreement.

The foregoing description

of the Lock-Up Agreements is not complete and is qualified in its entirety by reference to the full text of the form of Lock-Up Agreement,

a copy of which is included as Exhibit A to Exhibit 2.1 to this Current Report on Form 8-K, and the terms of which are incorporated herein

by reference.

The information furnished under this Item 7.01,

including Exhibit 99.1, shall not be deemed “filed” for purposes of Section 18 of the Exchange Act or otherwise

subject to the liabilities of that section, and shall not be deemed to be incorporated by reference into any filing under the Securities

Act or the Exchange Act, regardless of any general incorporation language in such filing. This Current Report on Form 8-K will not be

deemed an admission as to the materiality of any information furnished under this Item 7.01.

Important Information About

the Transactions and Where to Find It

In connection with the Transactions,

Parent intends to file with the SEC the Registration Statement, which will include a preliminary proxy statement of the Company and a

preliminary prospectus of Parent. After the Registration Statement is declared effective, the Company will mail a definitive proxy statement/prospectus

to its shareholders. This Current Report on Form 8-K does not contain all of the information that should be considered concerning the

Transactions and is not intended to form the basis of any investment decision or any other decision in respect of the Transactions. The

Company’s shareholders and other interested persons are urged to read, when available, the preliminary proxy statement/prospectus,

any amendments thereto and the definitive proxy statement/prospectus, as well as the other documents filed with the SEC in connection

with the Transactions, because these documents will contain important information about the Company, Parent, KQC Korea and the Transactions.

Shareholders will be able to obtain copies of the Registration Statement and the proxy statement/prospectus, without charge, once available,

at the SEC’s website at www.sec.gov or by directing a request to Charlton Aria Acquisition Corporation, 221 W 9th St #848, Wilmington,

DE 19801.

Korea, and their respective directors and executive officers, may, under SEC rules, be deemed to be participants in the solicitation of

more detailed information regarding the names and interests of the Company’s directors and executive officers in the Company’s

filings with the SEC, including its Annual Report on Form 10-K and the other documents filed by the Company with the SEC from time to

shareholders in connection with the Transactions, including a description of their direct and indirect interests, which may in some cases

be different from those of the Company’s shareholders generally, will be set forth in the proxy statement/prospectus when it becomes

made. No filing or response shall describe SPAC, the Sponsor, the Trust Account, the Redemptions or the Merger consideration without SPAC’s

prior written consent; provided that, if a party cannot respond within such ten (10) Business Day period, it shall promptly notify the

other party of the reason it cannot do so and the expected timing of its response.

at any time before the Closing any information relating to a party is discovered which should be set out in an amendment or supplement

to the Registration Statement, that party shall promptly notify the other and an appropriate amendment or supplement shall be filed and,

to the extent required by Law, disseminated to SPAC’s shareholders.

(d) Parent

shall consult with SPAC before including any projections, forecasts or other forward-looking financial information of any Group Company

applicable to de-SPAC transactions.

Section 5.5 PCAOB Audit.

(a) Engagement.

Parent shall, and shall cause KQC Korea to, engage an independent registered public accounting firm reasonably acceptable to SPAC as promptly

as practicable and no later than fifteen (15) Business Days after the date of this Agreement. The firm must be (i) registered with the

that limits the PCAOB’s ability to inspect it, and (iii) independent of the Group Companies under both the SEC’s and the PCAOB’s

and shall report to SPAC on progress not less frequently than every two (2) weeks.

Parent shall deliver audited consolidated financial statements of the Group Companies for each period required by Regulation S-X (including

Article 15 thereof) to be included in the Registration Statement, prepared in accordance with GAAP and audited in accordance with the

standards of the PCAOB, together with any reviewed interim financial statements required by Regulation S-X, no later than November 30,

2026.

(d) Refresh.

Parent shall deliver such additional, updated or re-audited financial statements, and cause such additional interim reviews to be completed,

as are necessary in order that the Registration Statement contains financial statements satisfying the age requirements of Regulation

S-X at the time the Registration Statement is declared effective. Without limiting the foregoing, if the Registration Statement has not

been declared effective on or before February 14, 2027, Parent shall deliver audited consolidated financial statements of the Group Companies

for the fiscal year ended December 31, 2026, audited in accordance with the standards of the PCAOB.

Meeting, shall distribute the Proxy Statement/Prospectus to its shareholders and shall solicit proxies in favour of the Transaction Proposals.

The board of directors of SPAC (the “SPAC Board”) shall recommend that shareholders vote in favour of the Transaction

Proposals (the “SPAC Board Recommendation”) and shall not withdraw or modify the SPAC Board Recommendation in a manner

adverse to Parent (a “Change of Recommendation”), except as required by its fiduciary duties.

(b) Notwithstanding

the foregoing or anything to the contrary in Section 5.6, at any time prior to the receipt of the SPAC Shareholder Approval, (i)

if the SPAC Board receives a bona fide written Acquisition Proposal that did not result from a breach of Section 5.8, the SPAC

Board and its Representatives may engage in discussions or negotiations with, and furnish non-public information to, the Person making

such Acquisition Proposal (provided that SPAC concurrently makes available to Parent any non-public information so furnished that was

not previously provided to Parent) if the SPAC Board has determined in good faith, after consultation with its financial adviser and outside

legal counsel, that such Acquisition Proposal constitutes or would reasonably be expected to lead to a Superior Proposal and that the

failure to take such action would be inconsistent with the fiduciary duties of the SPAC Board under applicable Law; and (ii) the SPAC

Board may effect a Change of Recommendation or cause SPAC to terminate this Agreement pursuant to Section 7.1(j) in order to enter

into a definitive agreement with respect to a Superior Proposal, but only if:

(i) SPAC

has provided Parent with written notice (a “Superior Proposal Notice”) at least five (5) Business Days prior to taking

such action, which notice shall identify the Person making the Superior Proposal, describe its material terms and conditions, and include

copies of all relevant transaction documents;

(ii) during

the five (5) Business Day period following delivery of the Superior Proposal Notice (the “Matching Period”), SPAC and

its Representatives have, if requested by Parent, negotiated in good faith with Parent and its Representatives regarding any revisions

to this Agreement proposed by Parent; and

(iii) at

the end of the Matching Period, the SPAC Board has determined in good faith, after consultation with its financial adviser and outside

legal counsel, that the Acquisition Proposal continues to constitute a Superior Proposal after giving effect to any revisions to this

Agreement proposed by Parent during the Matching Period, and that the failure to effect a Change of Recommendation or terminate this Agreement

would be inconsistent with the fiduciary duties of the SPAC Board under applicable Law.

at any time after delivery of a Superior Proposal Notice and prior to the expiration of the Matching Period the Acquisition Proposal is

amended in any material respect, SPAC shall deliver a new Superior Proposal Notice and the Matching Period shall recommence.

Section 5.7 Nasdaq Listing; Successor Issuer

best efforts to satisfy the initial listing requirements of Nasdaq, including the round lot holder, publicly held shares and market value

transfer agent to conduct a round lot holder analysis at an early stage and shall promptly notify SPAC of any indication that a listing

requirement may not be satisfied. The parties shall make the filings contemplated by Section 2.16(b) and Section 2.16(c)

on a timely basis.

Affiliates and Representatives not to, solicit, initiate, encourage or engage in any discussion or negotiation with respect to, or enter

into any agreement in respect of, any Acquisition Proposal. Each of the Parties will furthermore reasonably cooperate, and cause its respective

Representatives to reasonably cooperate, with the other party and its respective Representatives regarding all due diligence matters,

including document requests, and shall respond to reasonable due diligence requests within three (3) business days of receipt thereof.

Each party shall promptly, and in any event within two (2) Business Days, notify the other of any Acquisition Proposal received by it,

which notice shall identify the Person making it and describe its material terms and conditions and shall be accompanied by copies of

any written proposal. The receiving party shall keep the other reasonably informed of any change to the material terms of any Acquisition

Proposal. Nothing in this Section 5.8 limits the ability of the board of directors of SPAC to act as contemplated by the final

sentence of Section 5.6.

Section 5.9 Access to Information; Diligence;

Confidentiality.

(a) Each

party shall afford the other and its Representatives reasonable access, upon reasonable notice and during normal business hours, to its

properties, books, records and personnel, and shall maintain and continue to populate the virtual data room established in connection

with the transactions contemplated by this Agreement.

(b) Parent

shall, and shall cause each other Group Company to, (i) complete and return to SPAC all diligence questionnaires and respond to each due

diligence request provided by or on behalf of SPAC to Parent or any other Group Company prior to the date of this Agreement (to the extent

not already completed and returned), and (ii) complete and return to SPAC all diligence questionnaires and respond to each due diligence

request provided by or on behalf of SPAC to Parent or any Group Company after the date of this Agreement. All responses shall be accurate

and complete in all material respects as of the date provided. Any response shall include all documents and information reasonably responsive

to the applicable request. Parent shall supplement or update any previously delivered response promptly upon becoming aware that such

response is incomplete or inaccurate in any material respect.

shall cause the counsel of KQC Korea to deliver to SPAC, no later than fifteen (15) Business Days after the date of this Agreement, a

letter, in form and substance reasonably satisfactory to SPAC, addressed to SPAC and its counsel, confirming that SPAC and its counsel

may rely on the legal due diligence report prepared by such counsel for KQC Korea in connection with the Transactions (the “Reliance

Letter”), to the same extent as if such report had been prepared at the request of, and addressed to, SPAC. The Reliance Letter

shall not contain any qualifications, limitations or disclaimers that are not customary for reliance letters of this type. Parent shall,

and shall cause KQC Korea to, use reasonable best efforts to cause such Korean counsel to cooperate with SPAC and its counsel in responding

to any follow-up questions or requests for clarification arising from such due diligence report.

(d) The

Parties acknowledge and agree that the Confidentiality Agreement shall remain in full force and effect in accordance with its terms during

the period from the date of this Agreement until the earlier of the Closing and the valid termination of this Agreement. The terms of

the Confidentiality Agreement are hereby incorporated by reference and shall survive any termination of this Agreement in accordance with

Policy and the SPAC Fairness Opinion and (ii) any other De-SPAC Costs required to be incurred by applicable law, in connection with any

filings made with the SEC or Nasdaq or any Extension Costs. To the extent that any De-SPAC Costs were or are incurred by or on behalf

of SPAC, subject to the De-SPAC Cost Cap, Parent shall upon SPAC’s written request, pay such De-SPAC Cost to the applicable third

party or advance such funds to SPAC for further payment to the applicable third party. Parent shall not be entitled to reimbursement of

any De-SPAC Costs paid or incurred by or on behalf of SPAC.

prepared and delivered to Parent a detailed budget of anticipated De-SPAC Costs (the “Approved Budget”). To the extent

either Party becomes aware of any individual De-SPAC Cost that may exceed the applicable line item in the Approved Budget by more than

fifteen percent (15%), such Party shall promptly notify the other Parties whose prior written consent (not to be unreasonably withheld,

conditioned, or delayed) shall be required for such Party to incur such De-SPAC Cost. SPAC shall provide Parent with monthly reports of

good faith in seeking a PIPE Financing and any Backstop Arrangement, and shall consult with each other as to the terms, timing and identity

the prior written consent of the other, such consent not to be unreasonably withheld, conditioned or delayed; provided, that Parent’s

consent shall be deemed to be provided if Parent has not responded to SPAC’s written request for consent within three Business Days

of SPAC’s delivery of such request. The parties shall conduct any PIPE Financing and any Backstop Arrangement in a manner that (a)

qualifies for an exemption from registration under Section 4(a)(2) of the Securities Act and Regulation D thereunder, (b) does not involve

any general solicitation or general advertising, and (c) would not reasonably be expected to result in the integration of such offering

with the offering registered on the Registration Statement or otherwise jeopardise the availability of that exemption or the effectiveness

of the Registration Statement. Each party shall obtain customary accredited-investor representations from each investor.

Section 5.18 Public Announcements.

Neither party shall issue any

press release or make any public announcement in respect of the Transactions without the prior written consent of the other, except as

required to be filed pursuant to Rule 425 under the Securities Act or Rule 14a-12 under the Exchange Act, in each case on the date of

Section 9.10 Disclosure Schedules.

Disclosure of any item in any

to, any of the terms, conditions or provisions of, any Contract to which Sponsor is a party, except in the case of clauses (B) and (C)

by the Business Combination Agreement.

4. General.

Agreement is terminated in accordance with its terms prior to the Closing, and upon such termination this Agreement shall be null and

void and of no effect whatsoever, and the parties hereto shall have no obligations under this Agreement; provided, however,

(i) restrict, limit, prohibit or affect any actions or inactions by Sponsor or any representative of Sponsor, as applicable, serving

in the capacity of a director or officer of SPAC or any Subsidiary of SPAC, acting in such person’s capacity as a director or officer

of SPAC or any Subsidiary of SPAC (it being understood and agreed that the Business Combination Agreement contains provisions that govern

the actions or inactions by the directors and officers of SPAC with respect to the Merger and the other Transactions) or (ii) prohibit,

limit or restrict the exercise of any fiduciary duties as director or officer of SPAC that is otherwise permitted by, and done in compliance

with, the terms of the Business Combination Agreement (and in each case of clauses (i) and (ii), without limiting Sponsor’s

obligations hereunder in its capacity as a shareholder of SPAC).

(m) Affiliates.

In this Agreement, the term “Affiliate”, when used with respect to a particular Person, means any other Person

that directly or indirectly, through one or more intermediaries, Controls, is Controlled by or is under common Control with such Person.

“Control” means the possession, directly or indirectly, of the power to direct or cause the direction of the

management and policies of a Person, whether through the ownership of voting securities, by contract or otherwise, and “Controlled

by” and “under common Control with” have correlative meanings.

(n) No

Recourse. This Agreement may be enforced only against the parties that have executed and delivered it. No past, present or future

director, officer, employee, incorporator, member, partner, shareholder, Affiliate, agent, attorney or Representative of any party shall

have any liability for any obligation of that party under this Agreement.

(o) Headings;

Interpretation. The headings and subheadings in this Agreement are for convenience only and shall not be considered a part of or affect

the construction or interpretation of any provision of this Agreement. In this Agreement, unless the context otherwise requires: (i) any

pronoun used shall include the corresponding masculine, feminine or neuter forms, and the singular form of nouns, pronouns and verbs shall

include the plural and vice versa; (ii) the term “including” (and with correlative meaning “include”) shall be

deemed in each case to be followed by the words “without limitation”; (iii) the words “hereof,” “herein,”

“hereto,” and “hereby” and other words of similar import shall be deemed in each case to refer to this Agreement

as a whole and not to any particular section or other subdivision of this Agreement; (iv) the term “or” means “and /or”;

(v) the word “extent” in the phrase “to the extent” means the degree to which a subject or thing extends,

and such phrase shall not simply mean “if’; and (vi) references to “written” or “in writing” include

in electronic form. The parties have participated jointly in the negotiation and drafting of this Agreement. Consequently, in the event

an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties hereto,

and no presumption or burden of proof shall arise favoring or disfavoring any party hereto by virtue of the authorship of any provision

of this Agreement.

(p) Counterparts.

This Agreement may be executed in two or more counterparts, and by different parties in separate counterparts, with the same effect as

if all parties hereto had signed the same document, but all of which together shall constitute one and the same instrument. Copies of

executed counterparts of this Agreement transmitted by electronic transmission (including by email or in .pdf format) or facsimile as

well as electronically or digitally executed counterparts (such as DocuSign) shall have the same legal effect as original signatures and

shall be considered original executed counterparts of this Agreement.

(q) New

Securities. In the event that, during the period from the date hereof until the earlier of the Closing and the valid termination of

the Business Combination Agreement, (i) any SPAC Class A Ordinary Shares, Founder Shares, SPAC Rights or other securities of SPAC

are issued to Sponsor in respect of the Sponsor Shares pursuant to any stock or share dividend, stock split, share subdivision, recapitalization,

reclassification, combination or exchange of SPAC securities owned by Sponsor or otherwise, then such securities acquired by Sponsor shall

be subject to the terms of this Agreement to the same extent as if they constituted Sponsor Shares, or (ii) Sponsor purchases or otherwise

acquires beneficial ownership of, or acquires the right to vote, any SPAC Class A Ordinary Shares, Founder Shares, SPAC Rights or other

securities of SPAC after the date of this Agreement by any means not contemplated by Section 4(q)(i) herein, then such securities

shall be subject to the terms of Section 1 of this Agreement to the same extent as if they constituted Sponsor Shares owned by Sponsor

as of the date hereof.

Exhibit 10.2

PARENT SUPPORT AGREEMENT

This Parent Support Agreement

(this “Agreement”) is made as of October 6, 2026 by and among (i) CHARLTON ARIA ACQUISITION CORPORATION, a Cayman

Islands exempted company (“SPAC”), (ii) KQC QUANTUM, INC., a Delaware corporation (“Parent”),

and (iii) the undersigned stockholders of Parent (collectively, the “Holders” and each, a “Holder”).

Any capitalized term used but not defined in this Agreement will have the meaning ascribed to such term in the Business Combination Agreement,

dated as of the date hereof, by and among SPAC, Parent, KQC MS LIMITED, a Cayman Islands exempted company and wholly owned subsidiary

of Parent (“Merger Sub”), and KOREA QUANTUM COMPUTING CO., LTD. (“KQC Korea”) (as

it may be amended, supplemented, modified and/or restated from time to time, the “Business Combination Agreement”).

WHEREAS, concurrently

with the execution and delivery of this Agreement, SPAC, Parent, Merger Sub, KQC Korea and Sponsor are entering into the Business Combination

Agreement, pursuant to which, upon the consummation of the transactions contemplated thereby (the “Closing”),

among other matters, (a) immediately prior to, and conditioned upon, the Effective Time, Parent will effect the Pre-Closing Recapitalization;

and (b) Merger Sub will merge with and into SPAC, with SPAC surviving the Merger as a direct wholly owned subsidiary of Parent (collectively,

the “Transactions”);

WHEREAS, as of the

date hereof, each Holder is the sole record holder and sole beneficial (as such term is defined in Rule 13d-3 under the Exchange Act,

which meaning shall apply for all purposes of this Agreement whenever the term “beneficial” or “beneficially”

is used) owner of, and has full voting power over, the number of shares of common stock of Parent (“Parent Common Stock”)

set forth under such Holder’s name on the signature page hereto (such Holder’s Parent Common Stock shall be referred to herein

as such Holder’s “Subject Stock”); and

WHEREAS, as a condition

and inducement to SPAC’s willingness to enter into the Business Combination Agreement, SPAC has required that the Holders enter

into this Agreement.

NOW, THEREFORE, in

consideration of the premises set forth above, which are incorporated in this Agreement as if fully set forth below, and intending to

be legally bound hereby, the parties hereby agree as follows:

1. Covenant

to Vote in Favor of Transactions and Other Actions in Connection with the Transactions. Each Holder agrees, with respect to all of

the Subject Stock:

(a) during

the period from the date hereof until the earlier of the Closing and the valid termination of the Business Combination Agreement (the

“Interim Period”), at each meeting of the stockholders of Parent (the “Parent Stockholders”)

or any class or series thereof, and in each written consent or resolution of any of the Parent Stockholders in which such Holder is entitled

to vote or consent as a stockholder of Parent (which written consent shall be delivered promptly, and in any event within twenty-four

(24) hours after Parent requests such delivery), such Holder hereby unconditionally and irrevocably agrees to be present for such meeting

or otherwise be counted as present thereat for the purpose of establishing a quorum and to vote (in person or by proxy), or consent to

any action by written consent or resolution, in accordance with the applicable provisions of Parent’s organizational documents,

including its bylaws and certificate of incorporation, and with respect to, as applicable, the Subject Stock (i) in favor of the adoption

and approval of the Pre-Closing Recapitalization, the Merger, the Business Combination Agreement, the Ancillary Agreements, any amendments

to Parent’s Organizational Documents, and all of the other Transactions (and any actions required in furtherance thereof), (ii)

in favor of the other matters set forth in the Business Combination Agreement, and (iii) against: (A) any Acquisition Proposal and any

and all other proposals (x) for the acquisition of Parent, (y) that could reasonably be expected to delay or impair the ability of Parent

to consummate the Pre-Closing Recapitalization, the Merger or any of the other Transactions, or (z) which are in competition with or materially

inconsistent with the Business Combination Agreement or the Ancillary Agreements; (B) other than as contemplated by the Business Combination

Agreement or the Ancillary Agreements, any material change in (x) the present capitalization of Parent or any amendment of Parent’s

organizational documents or (y) Parent’s corporate structure or business; or (C) any other action or proposal involving any Group

Company that is intended, or would reasonably be expected, to prevent, impede, interfere with, delay, postpone or adversely affect in

any material respect the Transactions or would reasonably be expected to result in any of the conditions to the Closing under the Business

Combination Agreement not being fulfilled;

(b) to

promptly execute and deliver all related documentation and take such other action in support of the Pre-Closing Recapitalization, the

Merger, the Business Combination Agreement, any Ancillary Agreements and any of the other Transactions as shall reasonably be requested

by Parent or SPAC in order to carry out the terms and provisions of this Section 1, including (i) any actions by written consent

of the Parent Stockholders presented to such Holder, and (ii) any applicable Ancillary Agreements (including a Lock-Up Agreement, which

shall be entered into by certain Holders), customary instruments of conveyance and transfer, and any consent, waiver, governmental filing

and similar or related documents;

as contemplated by the Business Combination Agreement or the Ancillary Agreements, not make, or in any manner participate in, directly

or indirectly, a “solicitation” of “proxies” or consents (as such terms are used in the rules of the SEC) or powers

of attorney or similar rights to vote, or seek to advise or influence any Person with respect to the voting of, any Subject Stock in connection

with any vote or other action with respect to the Transactions, other than to recommend that the stockholders of Parent vote in favor

of adoption of the Business Combination Agreement and the Transactions and any other proposal the approval of which is a condition to

the obligations of the parties under the Business Combination Agreement (and any actions required in furtherance thereof and otherwise

as expressly provided by Section 1 of this Agreement);

(d) to

refrain from exercising any dissenters’ rights or rights of appraisal under applicable Law at any time with respect to the Pre-Closing

Recapitalization, the Merger, the Business Combination Agreement, the Ancillary Agreements and any of the Transactions; and

(e) that

each Holder hereby unconditionally and irrevocably waives any and all pre-emption rights, rights of first offer, rights of first refusal,

rights of participation, tag-along rights and all other similar rights that such Holder may have in respect of the Transactions, whether

such rights arise from Parent’s Organizational Documents, any other agreement, contract and/or arrangement (whether written or unwritten),

at law or otherwise.

2. Grant

of Proxy. Each Holder, with respect to all of such Holder’s Subject Stock, hereby irrevocably grants to, and appoints, SPAC

and any designee of SPAC (determined in SPAC’s sole discretion) as such Holder’s attorney-in-fact and proxy, with full power

of substitution and resubstitution, for and in such Holder’s name, to vote, or cause to be voted (including by proxy or written

consent, if applicable) any Subject Stock owned (whether beneficially or of record) by such Holder as of the date hereof and as of immediately

prior to the Effective Time, with respect to any vote related to the Business Combination Agreement and the Transactions. The proxy granted

by such Holder pursuant to this Section 2 is irrevocable and is granted in consideration of SPAC entering into this Agreement and

the Business Combination Agreement and incurring certain related fees and expenses. Each Holder hereby affirms that such irrevocable proxy

is coupled with an interest by reason of the Business Combination Agreement and, except upon the termination of this Agreement in accordance

with Section 5(a), is intended to be irrevocable. Each Holder agrees, until this Agreement is terminated in accordance with Section

5(a), to vote its Subject Stock in accordance with Section 1.

3. Other

Covenants.

(a) No

Transfers. Each Holder agrees that during the Interim Period it shall not, and shall cause its Affiliates not to, without SPAC’s

prior written consent, (A) offer for sale, sell (including short sales), transfer, tender, pledge, encumber, assign or otherwise dispose

of (including by gift) (collectively, a “Transfer”) any or all of the Subject Stock; (B) enter into any contract,

option, derivative, hedging or other agreement or arrangement or understanding (including any profit-sharing arrangement) with respect

to, or consent to, a Transfer of, any or all of the Subject Stock; (C) grant any proxies or powers of attorney with respect to any or

all of the Subject Stock; (D) permit to exist any lien of any nature whatsoever (other than those imposed by this Agreement, applicable

securities Laws or Parent’s organizational documents, as in effect on the date hereof, or disclosed under such Holder’s name

on the signature page hereto (the “Disclosed Exceptions”)) with respect to any or all of the Subject Stock;

(E) except as provided in this Agreement, deposit any Subject Stock in a voting trust or subject any Subject Stock to any arrangement

or agreement with respect to the voting of such Subject Stock (other than a Post-Closing Stockholders Agreement), unless specifically

requested to do so by Parent and SPAC in connection with the Business Combination Agreement, the Ancillary Agreements or the Transactions;

or (F) take any action that would have the effect of preventing, impeding, interfering with or adversely affecting such Holder’s

ability to perform its obligations under this Agreement. Parent hereby agrees that it shall not permit any Transfer of the Subject Stock

in violation of this Agreement. Each Holder agrees with, and covenants to, SPAC that such Holder shall not request that Parent register

the Transfer (book-entry or otherwise) of any certificate or uncertificated share representing any Subject Stock during the Interim Period

without the prior written consent of SPAC, and Parent hereby agrees that it shall not effect any such Transfer.

(b) Changes

to Subject Stock. In the event of an equity distribution, or any change in the equity interests of Parent by reason of any equity

distribution, equity split, recapitalization, combination, conversion, exchange of equity interests or the like, the term “Subject

Stock” shall be deemed to refer to and include the Subject Stock as well as all such equity distributions and any securities into

which or for which any or all of the Subject Stock may be changed or exchanged or which are received in such transaction. Each Holder

agrees during the Interim Period to notify SPAC and Parent promptly in writing of the number and type of any changes to such Holder’s

ownership of or voting rights with respect to the Subject Stock, upon such Holder’s acquisition or commitment to acquire any additional

Subject Stock or upon any other changes involving such Holder relating to the equity interests of Parent or securities convertible into

or exercisable for equity interests of Parent.

with Business Combination Agreement. Each Holder agrees during the Interim Period not to take or agree or commit to take any action

that would make any representation or warranty of such Holder contained in this Agreement inaccurate in any material respect. Each Holder

further agrees that it shall use its commercially reasonable efforts to cooperate with SPAC to effect the Merger, all other Transactions,

the Business Combination Agreement, the Ancillary Agreements and the provisions of this Agreement. During the Interim Period, each Holder

shall not authorize or permit any of its Representatives to, directly or indirectly, take any action that Parent is prohibited from taking

pursuant to Section 5.1 of the Business Combination Agreement (unless SPAC shall have consented thereto).

(d) Registration

Statement. During the Interim Period, each Holder agrees to provide to SPAC, Parent and their respective Representatives any information

regarding such Holder or the Subject Stock that is reasonably requested by SPAC, Parent or their respective Representatives for inclusion

in the Registration Statement.

(e) Publicity.

No Holder shall issue any press release or otherwise make any public statements with respect to the Transactions or the transactions contemplated

herein without the prior written approval of Parent and SPAC. Each Holder hereby authorizes Parent and SPAC to publish and disclose in

any announcement or disclosure required by the SEC, Nasdaq or the Registration Statement (including all documents and schedules filed

with the SEC in connection with the foregoing), such Holder’s identity and ownership of the Subject Stock and the nature of such

Holder’s commitments and agreements under this Agreement, the Business Combination Agreement and any other Ancillary Agreements.

(f) No

Solicitation. Each Holder agrees to be bound by and subject to Section 5.8 of the Business Combination Agreement to the same extent

as such provisions apply to Parent, as if such Holder was a party thereto.

4. Representations

and Warranties of Holders. Each Holder hereby represents and warrants to SPAC and Parent as follows:

(a) Binding

Agreement. Such Holder (i) if a natural person, is of legal age to execute this Agreement and is legally competent to do so and (ii)

if not a natural person, is (A) a corporation, limited liability company, company or partnership duly organized and validly existing under

the Laws of the jurisdiction of its organization and (B) has all necessary power and authority to execute and deliver this Agreement,

to perform its obligations hereunder and to consummate the transactions contemplated hereby. If such Holder is not a natural person, the

execution and delivery of this Agreement, the performance of its obligations hereunder and the consummation of the transactions contemplated

hereby by such Holder have been duly authorized by all necessary corporate, limited liability or partnership action on the part of such

Holder, as applicable. This Agreement, assuming due authorization, execution and delivery hereof by the other parties hereto, constitutes

a legal, valid and binding obligation of such Holder, enforceable against such Holder in accordance with its terms (except as such enforceability

may be limited by bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and other similar Laws of general applicability

relating to or affecting creditors’ rights, and to general equitable principles). Such Holder understands and acknowledges that

SPAC is entering into the Business Combination Agreement in reliance upon the execution and delivery of this Agreement by such Holder.

(b) Ownership

of Subject Stock. As of the date hereof, such Holder has beneficial ownership over the Subject Stock set forth under such Holder’s

name on the signature page hereto, is the lawful owner of such Subject Stock, has the sole power to vote or cause to be voted such Subject

Stock (to the extent the Subject Stock has associated voting rights), and has good and valid title to such Subject Stock, free and clear

of any and all pledges, mortgages, encumbrances, charges, proxies, voting agreements, liens, adverse claims, options, security interests

and demands of any nature or kind whatsoever, other than those imposed by this Agreement, applicable securities Laws or Parent’s

organizational documents, as in effect on the date hereof, and other than the Disclosed Exceptions. There are no claims for finder’s

fees or brokerage commission or other like payments in connection with this Agreement or the transactions contemplated hereby payable

by such Holder pursuant to arrangements made by such Holder. Except for the Subject Stock of Parent set forth under such Holder’s

name on the signature page hereto and except for the Disclosed Exceptions, as of the date of this Agreement, such Holder is not a beneficial

owner or record holder of any: (i) equity securities of Parent, (ii) securities of Parent having the right to vote on any matters on which

the holders of equity securities of Parent may vote or which are convertible into or exchangeable for, at any time, equity securities

of Parent or (iii) options, warrants or other rights to acquire from Parent any equity securities or securities convertible into or exchangeable

for equity securities of Parent.

Conflicts. No filing with, or notification to, any Governmental Authority, and no consent, approval, authorization or permit of any

other Person is necessary for the execution of this Agreement by such Holder, the performance of its obligations hereunder or the consummation

by it of the transactions contemplated hereby. None of the execution and delivery of this Agreement by such Holder, the performance of

its obligations hereunder or the consummation by it of the transactions contemplated hereby shall (i) conflict with or result in any breach

of the certificate of incorporation, bylaws or other comparable organizational documents of such Holder, if applicable, (ii) result in,

or give rise to, a violation or breach of or a default under any of the terms of any contract or obligation to which such Holder is a

party or by which such Holder or any of the Subject Stock or its other assets may be bound, or (iii) violate any applicable Law or Order,

except for any of the foregoing in clauses (i) through (iii) as would not reasonably be expected to impair such Holder’s ability

to perform its obligations under this Agreement in any material respect.

(d) No

Inconsistent Agreements. Such Holder hereby covenants and agrees that, except for this Agreement, such Holder (i) has not entered

into, nor will enter into at any time while this Agreement remains in effect, any voting agreement or voting trust with respect to the

Subject Stock (other than a voting, stockholders’ or similar agreement among Holders and/or other stockholders of Parent that by

its terms becomes effective only from and after the Closing and does not affect the voting or Transfer of the Subject Stock during the

Interim Period, a “Post-Closing Stockholders Agreement”), (ii) has not granted, nor will grant at any time while this

Agreement remains in effect, a proxy, a consent or power of attorney with respect to the Subject Stock (other than under a Post-Closing

Stockholders Agreement) and (iii) except for the Disclosed Exceptions, has not entered into any agreement or knowingly taken any action

(nor will enter into any agreement or knowingly take any action) that would make any representation or warranty of such Holder contained

herein untrue or incorrect in any material respect or have the effect of preventing such Holder from performing any of its material obligations

under this Agreement.

5. Waiver

and Release of Claims. Each Holder covenants and agrees as follows:

(a) Subject

to and conditioned upon the Closing, effective as of the Closing (and subject to the limitations set forth in Section 5(d)), each

Holder, on behalf of itself and its Affiliates and its and their respective successors, assigns, representatives, administrators, executors

and agents, and any other Person claiming by, through, or under any of the foregoing (each a “Releasing Party”

and, collectively, the “Releasing Parties”; provided, for the avoidance of doubt, that SPAC shall not be deemed

a Releasing Party hereunder), does hereby unconditionally and irrevocably release, waive and forever discharge SPAC, Parent, and each

of their past and present directors, officers, employees, agents, predecessors, successors, assigns, and Subsidiaries, from any and all

past or present claims, demands, damages, judgments, causes of action and liabilities of any nature whatsoever, whether or not known,

suspected or claimed, arising directly or indirectly from any act, omission, event or transaction occurring (or any circumstances existing)

at or prior to the Closing, in each case to the extent arising out of or relating to such Holder’s capacity as a current or former

stockholder of Parent or holder of any other equity securities of Parent (or securities convertible into equity securities of Parent)

(each a “Claim” and, collectively, the “Claims”).

(b) Holder

acknowledges that it may hereafter discover facts in addition to or different from those which it now knows or believes to be true with

respect to the subject matter of this Agreement, and that it may hereafter come to have a different understanding of the law that may

apply to potential claims which it is releasing hereunder, but it affirms that, except as is otherwise specifically provided herein, it

is its intention to fully, finally and forever settle and release any and all Claims. In furtherance of this intention, Holder acknowledges

that the releases contained herein shall be and remain in effect as full and complete general releases with respect to the specified subject

matter notwithstanding the discovery or existence of any such additional facts or different understandings of law.

understands that Holder has the right not to release existing Claims of which Holder is not aware, unless Holder voluntarily chooses to

waive this right. Having been so apprised, Holder elects to assume all risks for Claims that exist, existed or may hereafter exist in

its favor, known or unknown, suspected or unsuspected, arising out of or related to claims or other matters purported to be released pursuant

to this Section 5, in each case, effective as of the Closing. Holder acknowledges and agrees that the foregoing waiver is an essential

and material term of the release provided pursuant to this Section 5 and that, without such waiver, SPAC and Parent would not have

agreed to the terms of this Agreement.

(d) Notwithstanding

the foregoing provisions of this Section 5 or anything to the contrary set forth herein, the Releasing Parties do not release or

discharge, and each Releasing Party expressly does not release or discharge: (i) any Claims that arise under or are based upon the terms

of the Business Combination Agreement, this Agreement, any of the Ancillary Agreements, or any other document, certificate or contract

executed or delivered in connection with the Business Combination Agreement, as each such agreement or instrument may be amended in accordance

with its terms and the terms set forth in (A) the Business Combination Agreement or (B) this Agreement or the other Ancillary Agreements

(if and to the extent applicable), (ii) any Claims for indemnification, exculpation, contribution, set-off, reimbursement, advancement

of expenses or similar rights pursuant to any organizational document of Parent or KQC Korea or any indemnity or similar agreement entered

into by Parent or KQC Korea with or for the benefit of a Releasing Party set forth on under such Holder’s name on the signature

page hereto, in each case in effect immediately prior to the Closing, or any rights or Claims under any applicable insurance policy (including

any directors’ and officers’ liability insurance policy or tail policy), including any such rights or Claims of a Releasing

Party arising from service as a present or former director or officer of Parent or KQC Korea, and including, in each case, protection

in respect of acts, omissions, events or circumstances occurring or existing at or prior to the Closing, whether or not such rights or

Claims are contemplated by or fall within the scope of Section 5.19 of the Business Combination Agreement; provided that this clause (ii)

preserves rights otherwise available under the applicable documents, agreements and policies, subject to their respective terms, and does

not itself create or expand any indemnification, advancement or insurance obligation or amend Section 5.19 or Section 9.4 of the Business

Combination Agreement, (iii) any Claims for compensation, reimbursement of expenses or benefits payable to such Holder in his, her or

its capacity as an officer, director, employee, consultant or contractor of any Group Company; or (iv) any Claims for obligations pursuant

to, or other rights set forth in, any employment or similar agreement between Holder, on the one hand, and any Group Company, on the other

hand, together with any other agreements, documents, instruments or certificates contemplated by the foregoing, as well as any other employment

related rights that such Holder has by Contract or pursuant to applicable Law.

6. Miscellaneous.

(a) Termination.

Notwithstanding anything to the contrary contained herein, this Agreement shall automatically terminate, and none of SPAC, Parent or any

Holder shall have any rights or obligations hereunder, upon the earliest to occur of (i) the mutual written consent of SPAC and Parent,

(ii) the Effective Time (following the performance of the obligations of the parties hereunder required to be performed at or prior to

the Effective Time), or (iii) the date of termination of the Business Combination Agreement in accordance with its terms. The termination

of this Agreement shall not prevent any party hereunder from seeking any remedies (at law or in equity) against another party hereto or

relieve such party from liability for such party’s breach of any terms of this Agreement. Notwithstanding anything to the contrary

herein, the provisions of this Section 6 shall survive the termination of this Agreement.

(b) Binding

Effect; Assignment. This Agreement and all of the provisions hereof shall be binding upon and inure to the benefit of the parties

hereto and their respective permitted successors and assigns. This Agreement and all obligations of each Holder are personal to such Holder

and may not be assigned, transferred or delegated by operation of Law or otherwise without the prior written consent of SPAC and Parent,

and any purported assignment, transfer or delegation without such consent shall be null and void; provided that no such assignment

shall relieve the assigning party of its obligations hereunder. Each of Parent and SPAC may freely assign any or all of its rights under

this Agreement, in whole or in part, to any successor entity (whether by merger, consolidation, equity sale, asset sale or otherwise)

without obtaining the consent or approval of any Holder.

Parties. Nothing contained in this Agreement or in any instrument or document executed by any party in connection with the transactions

contemplated hereby shall create any rights in, or be deemed to have been executed for the benefit of, any person that is not a party

hereto or thereto or a successor or permitted assign of such a party.

(d) Governing

Law; Jurisdiction. This Agreement and any dispute or controversy arising out of or relating to this Agreement shall be governed by

and construed in accordance with the Laws of the State of New York without regard to the conflict of laws principles thereof. All Actions

arising out of or relating to this Agreement shall be heard and determined exclusively in any state or federal court located in New York,

New York (or in any appellate court thereof) (the “Specified Courts”). Each party hereto hereby (i) submits

to the exclusive jurisdiction of any Specified Courts for the purpose of any Action arising out of or relating to this Agreement brought

by any party hereto and (ii) irrevocably waives, and agrees not to assert by way of motion, defense or otherwise, in any such Action,

any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from

attachment or execution, that the Action is brought in an inconvenient forum, that the venue of the Action is improper, or that this Agreement

or the transactions contemplated hereby may not be enforced in or by any Specified Courts. Each party agrees that a final judgment in

any Action shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law.

Each party irrevocably consents to the service of the summons and complaint and any other process in any other Action relating to the

transactions contemplated by this Agreement, on behalf of itself, or its property, by personal delivery of copies of such process to such

party at the applicable address set forth in Section 6(g) (and in the case of any Holder, the address set forth on such Holder’s

signature page). Nothing in this Section 6(d) shall affect the right of any party to serve legal process in any other manner permitted

by applicable Law.

(e) WAIVER

OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW ANY RIGHT IT MAY HAVE TO

A TRIAL BY JURY WITH RESPECT TO ANY ACTION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS

CONTEMPLATED HEREBY. EACH PARTY HERETO (i) CERTIFIES THAT NO REPRESENTATIVE OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE,

THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF ANY ACTION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (ii) ACKNOWLEDGES THAT IT AND THE

OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS

SECTION 6(e).

(f) Interpretation.

The titles and subtitles contained in this Agreement are solely for the purpose of reference, are not part of the agreement of the parties

and shall not in any way affect the meaning or interpretation of this Agreement. In this Agreement, unless the context otherwise requires:

(i) any pronoun used in this Agreement shall include the corresponding masculine, feminine or neuter forms, and the singular form of nouns,

pronouns and verbs, including any defined terms, include the plural and vice versa; (ii) “including” (and with correlative

meaning “include”) means including without limiting the generality of any description preceding or succeeding such term and

shall be deemed in each case to be followed by the words “without limitation”; (iii) the words “herein,” “hereto,”

and “hereby” and other words of similar import in this Agreement shall be deemed in each case to refer to this Agreement as

a whole and not to any particular section or other subdivision of this Agreement; (iv) the word “if” and other words of similar

import when used herein shall be deemed in each case to be followed by the phrase “and only if”; and (v) the term “or”

means “and/or”. The parties have participated jointly in the negotiation and drafting of this Agreement. Consequently, in

the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the

parties hereto, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any

provision of this Agreement.

delivered (i) in person, (ii) by electronic means (including email), with affirmative confirmation of receipt, (iii) one (1) Business

contemplated by this Agreement.

(n) Entire

Agreement. This Agreement (together with the Business Combination Agreement to the extent referred to herein) constitutes the full

and entire understanding and agreement among the parties with respect to the subject matter hereof, and any other written or oral agreement

Exhibit 99.1

KQC

Quantum, Inc. and Charlton Aria Acquisition Corporation Announce Definitive Business Combination Agreement to Take Korea’s Enterprise

Quantum Computing and Quantum-Safe Security Company Public on Nasdaq

KQC

helps enterprises put quantum computing and post-quantum cryptography to work through Qubiteer, its AI-driven hybrid quantum platform,

access to multiple quantum technologies, and quantum-safe security products

Combined

company, KQC Quantum, Inc., expected to list on Nasdaq; proceeds to fund product commercialization and the conversion of customer pilots

into deployments

Transaction

Highlights

● Enterprise

quantum, built for adoption. KQC works in the layer between quantum hardware and industry:

it defines customer problems, builds the models, runs them on the most suitable classical,

quantum or hybrid resource, and integrates the results. Its Qubiteer platform, currently

in development, uses AI to turn business problems into solvable models and to select the

best-fit solver.

● Hardware-agnostic

by design. KQC provides access to third party quantum systems across superconducting,

trapped-ion, neutral-atom, photonic and quantum annealing platforms, allowing it to match

each workload to the most suitable technology as quantum hardware evolves.

● Industrial

and financial references. KQC has completed quantum computing projects with POSCO Holdings

in battery materials and with Busan Transportation Corporation in urban rail scheduling,

and paid post-quantum security proofs of concept with Industrial Bank of Korea (IBK) and

LS ITC.

● A

second growth engine in quantum-safe security. Following the finalization of the first

U.S. post-quantum cryptography standards in 2024, KQC supplies and integrates quantum-safe

hardware security, authentication and key-management products for enterprises beginning their

migration.

● Transaction

terms. The transaction values KQC at a pre-money equity value of $80 million, with KQC

shareholders receiving shares of the combined company valued at $11.00 per share. Existing

KQC shareholders will roll 100% of their equity into the combined company.

● Capital.

Charlton Aria’s trust account held approximately $93.5 million as of September 25,

2026. The cash available at closing will depend on redemptions by Charlton Aria shareholders.

● Timing.

The transaction is expected to close in the first half of 2027 subject to approval by Charlton

Aria shareholders, an extension of Charlton Aria’s business combination deadline and

other customary closing conditions.

WILMINGTON,

Del. and BUSAN, South Korea, October 7, 2026 (GLOBE NEWSWIRE) -- KQC Quantum, Inc. (“KQC Parent”), the Delaware parent

company of Korea Quantum Computing Co., Ltd. (“KQC” or the “Company”), which helps enterprises adopt quantum

computing and quantum-safe security, and Charlton Aria Acquisition Corporation (Nasdaq: CHAR) (“Charlton Aria”), a publicly

traded special purpose acquisition company, today announced that they have entered into a definitive business combination agreement (the

“Business Combination Agreement”).

Upon

completion of the proposed transaction (the “Business Combination”), Charlton Aria will become a wholly owned subsidiary

of KQC Parent, with shares of common stock of the combined company expected to trade on The Nasdaq Stock Market under the ticker symbol

“KQC.”

The

Business Combination is expected to give KQC access to the U.S. public capital markets to fund its next stage of commercialization: engineering

Qubiteer and its quantum-safe security platform into repeatable products, building the teams that turn customer pilots and proofs of

concept into deployments, and completing product security certifications.

Putting

Quantum Technology to Work for Enterprises

KQC

was founded in Busan in 2021 on the view that enterprises adopt quantum technology not because of hardware milestones alone, but when

a real business problem can be expressed in a form a computer can solve, run on the right resource, and delivered in a way that fits

their systems and security requirements. KQC does not build quantum processors. It focuses on the work between hardware and industry

— problem definition, mathematical modeling, solver selection, execution and integration — and on protecting enterprise systems

as quantum computing advances.

Qubiteer:

AI-driven hybrid quantum computing

Currently

in development with a demo launched in June 2026, Qubiteer lets a user describe a business problem and its constraints. AI builds and

checks the corresponding mathematical model, Qubiteer compares classical, quantum and hybrid solvers for the workload, and results are

presented against the business objective. Because the platform selects the approach that fits each problem, customers can benefit from

today’s classical and hybrid methods while gaining a path to quantum hardware as it improves. Initial application areas include

industrial optimization and scheduling.

Quantum

computing services and multi-vendor access

KQC

provides applied research, modeling and quantum computing access to enterprise and research customers. As an example, it works with D-Wave’s

quantum annealing systems through D-Wave’s Leap quantum cloud service. Since 2022, KQC has carried out projects across materials,

transportation and pharmaceutical research, including the search for high-performance cathode materials for secondary batteries with

POSCO Holdings, which combined quantum optimization with first-principles calculations, and train and crew scheduling optimization for

Busan’s urban rail network with Busan Transportation Corporation under a national R&D program supported by Korea’s Ministry

of Science and ICT. KQC researchers have also co-authored peer-reviewed research applying quantum annealing to real-world data.

Quantum-safe

security

Organizations

need to replace the public-key cryptography that protects today’s systems before large-scale quantum computers can break it, and

because sensitive data can be captured now and decrypted later, that transition has already begun. The U.S. National Institute of Standards

and Technology finalized its first three post-quantum cryptography standards in August 2024. KQC helps enterprises plan and carry out

this migration. Through partnerships, KQC supplies and integrates post-quantum hardware security modules and key and secrets management.

It is also developing its own products for hardware-based authentication and embedded key protection, as well as QuantumSpan,

a platform designed to help enterprises inventory their cryptographic assets and manage migration across their existing security infrastructure.

KQC has completed paid post-quantum security proofs of concept with Industrial Bank of Korea (IBK) and LS ITC.

Commercialization

and Growth Strategy

KQC

grows through repeatable customer outcomes. In quantum computing, it starts with a defined customer problem, demonstrates value against

a classical baseline, and then expands Qubiteer usage by reusing validated models across related workloads. In security, it starts with

a priority system, validates compatibility in a paid pilot, deploys the selected products, and extends coverage and support over time,

with QuantumSpan designed to turn migration projects into platform subscriptions.

KQC

operates in a market shaped by national policy: Korea has adopted a national quantum strategy and a dedicated law to promote quantum

science, technology and industry. KQC is also building partner channels outside Korea, beginning in Southeast Asia with a memorandum

of understanding with GEM announced in September 2026.

Following

completion of the Business Combination, KQC expects to use the proceeds for product engineering for Qubiteer, QuantumSpan and its security

products; customer delivery and industry-solution teams; completing security certifications, including KCMVP; public-company readiness;

and working capital and general corporate purposes.

Management

Commentary

Hoon Kweon, Chairman of KQC, said: “Today’s agreement is an important step for KQC. When we founded the company in 2021,

we believed enterprises would adopt quantum technology not because of hardware milestones, but when someone could take a real business

problem, connect it to the right computing and security tools, and deliver a result they could use. That is the work we have been doing

with Korean industrial and financial customers, and Qubiteer and our security products are designed to make it repeatable. A Nasdaq listing

gives us the capital and the visibility to bring this model to more customers, in Korea and beyond, and we are excited to continue accelerating

customer adoption.”

Jung

Min Lee, Chairman and Chief Executive Officer of Charlton Aria, said: “We looked for a company with real customer engagements,

products in the market and a clear use for public capital. KQC has built its business around what enterprises can use today: software

that makes hybrid quantum computing practical, and security products for a migration that is already under way. We believe this transaction

gives KQC the resources for its next stage of growth.”

Transaction

Overview

The

Business Combination Agreement has been approved by the boards of directors of KQC and Charlton Aria. Under the agreement, a newly formed

Cayman Islands subsidiary of KQC Parent (“Merger Sub”) will merge with and into Charlton Aria, with Charlton Aria surviving

as a wholly owned subsidiary of KQC Parent. Charlton Aria shareholders will receive one share of KQC common stock for each Class A ordinary

share they hold, and holders of Charlton Aria rights will receive one-eighth of one share of KQC common stock for each right.

The

transaction values KQC at a pre-money equity value of approximately $80 million, at $11.00 per share. The transaction implies a pro forma

equity value of approximately $215 million, based on the assumptions set out in the investor presentation.

Charlton

Aria’s trust account held approximately $93.5 million as of September 25, 2026. The cash available to the combined company at closing

will depend on the level of redemptions by Charlton Aria shareholders, including in connection with the extension meeting described below.

The Business Combination Agreement includes a minimum cash condition of $30 million.

The

cash available at closing is expected to be used for the purposes described above, to pay transaction expenses, and for working capital

and general corporate purposes.

Existing

KQC shareholders will roll 100% of their equity into the combined company and are expected to own approximately 37% of the combined company

at closing assuming no redemptions by Charlton Aria shareholders, and approximately 47% assuming a 50% redemption scenario.

The

Business Combination is expected to close during the first half of 2027, subject to approval by Charlton Aria shareholders, the registration

statement on Form S-4 being declared effective by the U.S. Securities and Exchange Commission (“SEC”), approval of KQC’s

common stock for listing on Nasdaq, satisfaction of the minimum cash condition, and other customary closing conditions.

Charlton

Aria must complete its initial business combination by October 25, 2026 unless its shareholders approve an extension. Charlton Aria intends

to call an extraordinary general meeting of its shareholders to approve an extension of that date to allow time to complete the Business

Combination. Details will be set out in a proxy statement to be filed with the SEC.

Additional

information about the proposed transaction, including a copy of the Business Combination Agreement, will be provided in Charlton Aria’s

Current Report on Form 8-K to be filed with the SEC and available at www.sec.gov. KQC intends to file with the SEC a registration statement

on Form S-4, which will include a proxy statement of Charlton Aria and a prospectus of KQC relating to the Business Combination.
