We note you have filed a short-form tax opinion as Exhibit 8.1 to your registration statement. Accordingly, please remove any statement in your disclosure that assumes the material tax consequences at issue (e.g., "Assuming the DPCM Merger so qualifies. . . a U.S. holder that exchanges DPCM Class A Shares for D-Wave Quantum Common Shares in the DPCM Merger should not recognize any gain or loss on such exchange."). State clearly that the DPCM Merger will qualify as an exchange governed by Section 351 of the U.S. Tax Code and whether U.S. holders who exchange DPCM Class A Shares for D- Wave Quantum Common Shares in the merger will recognize gain or loss on such an exchange. For further guidance see Staff Legal Bulletin No. 19 (October 14, 2011) and Item 601(b)(8) of Regulation S-K. If there is uncertainty regarding the tax treatment of the business combination, counsel s opinion should discuss the degree of uncertainty.

You disclose on page 201 that after consummation of the Transaction and PIPE financing, you expect cash balances of approximately $128.2 million, assuming the Maximum Redemption Scenario, or $318.3 million, assuming the No Redemption Scenario. These figures do not appear consistent with pro forma cash balances presented on page 151. Please revise as appropriate to clarify the reason for this apparent discrepancy.

Please tell us and revise your filing to explain the reason for this discrepancy.

Please disclose how you received notice from the Firms, the amount of any fees that have already been paid to the Firms, and why each waiver was agreed to. Separately state the amount of fees waived by each Firm, not solely in the aggregate. In addition, with respect to each such resignation: Please clarify the role that each Firm played in any part of the Transaction (i.e., the identification or evaluation of business combination targets) as well as the current relationship between the Firms and the merger parties (i.e. whether there are other relationships with any of the Firms after the resignations). Disclose both the extent of the work already performed and the work agreed to be performed by each Firm prior to its resignation. Revise the background of the Transaction to clearly note when any of the Firms were present in discussions or at board meetings and qualify their presence by noting they subsequently resigned. Discuss the potential impact on the Transaction related to the resignation of the Firms, including, but not limited to, any impact on the PIPE financing. For example, if any of the Firms would have played a role in the closing, please revise to identify the party who will be filling any such role. Disclose in the forepart of the filing that the Firms claim no remaining role in your business combination transaction and have affirmatively disclaimed any responsibility for any of the disclosure in this registration statement. Please disclose whether any of the Firms were involved in the preparation of any disclosure that is included in the Form S-4 registration statement, including but not limited to any analysis underlying disclosure in the registration statement. If so, clarify the involvement of any such Firm, whether it has retracted any work product associated with the transaction, and the risk of such withdrawal and reliance on such Firm's expertise. Disclose whether any of the Firms provided you with any reasons for its respective resignation or why it was unable to complete its respective engagement. If there was no dialogue and/or you did not seek out the reasons why such Firm was resigning (and waiving deferred fees, as applicable) or unable to complete its respective engagement, despite already providing and/or completing their services, please indicate so in your registration statement.

Clarify the unusual nature of each fee waiver and the impact of it on the evaluation of the Transaction. 12. Please disclose what consideration the DPCM Board has given to reconsidering its assessment of the Transaction given the subsequent resignation of the Firms. Expand your disclosure to address the DPCM Board's consideration of the Transaction without the advice of the Firms and disclose the impact this will have on investors. 13. We note your risk factor on page 80 addressing the resignation of Morgan Stanley, Citi and UBS in their advisory roles in connection with the Transaction. Please disclose whether UBS advised it has resigned in every capacity in which they were described in the registration statement. If so, please expand your disclosure to address this fact. In that regard, we note your disclosure on page 110 that UBS "has an interest in DPCM completing a business combination that will result in the payment of the deferred underwriting commission."

Please disclose any ongoing obligations of the parties pursuant to the engagement letter that will survive termination of the engagement, such as indemnification provisions, rights of first refusal, and lockups, and discuss the impacts of those obligations on the company in the registration statement. Please also provide us with any correspondence between each Firm and DPCM and/or D-Wave relating to such Firm's resignation. 15. Please provide us with a letter from each Firm stating whether it agrees with the statements made in your proxy statement/prospectus related to their resignation and, if not, stating the respects in which they do not agree. Please revise your disclosure accordingly to reflect that you have discussed the disclosure with such Firm and it either Emil Michael D-Wave Quantum Inc. June 9, 2022 Page 6 agrees or does not agree with the conclusions and the risks associated with such outcome. If any such Firm does not respond, please revise your disclosure to indicate you have asked and not received a response and disclose the risks to investors. Additionally, please indicate that such Firm withdrew from its respective role(s) in your transaction and forfeited its fees, if applicable, and that such Firm refused to discuss the reasons for its resignation and forfeiture of fees, if applicable, with management. The disclosure should clarify whether each Firm performed substantially all the work to earn its fees. 16. Please revise your disclosure to highlight for investors that each Firm s withdrawal indicates that it does not want to be associated with the disclosure or underlying business analysis related to the transaction. In addition, your disclosure should caution investors that they should not place any reliance on the fact that the Firms have been previously involved with the transaction.
