Item 7.01 Regulation FD Disclosure. On August 18, 2026, D-Wave Quantum Inc. (“D-Wave” or the “Company”) announced its participation as a platinum sponsor of Quantum World Congress 2026, taking place September 23-25 in College Park, Maryland. At Quantum World Congress, D-Wave will demonstrate that the quantum era is multi-platform with different quantum computing technologies to address different types of computational problems. The Company will present results from annealing quantum computing applications solving complex commercial and public-sector optimization problems today. In addition, it will provide updates on its dual-rail gate-model architecture, designed to reduce the cost and complexity of quantum error correction, a critical requirement for enabling applications well suited to gate-model quantum computing, such as quantum chemistry and materials simulation. A copy of the press release is attached as Exhibit 99.1. The information in this Item 7.01 to this Current Report on Form 8-K, including Exhibit 99.1, is intended to be furnished and shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall such information be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference in such a filing.
