D-Wave Quantum Inc. named Greg Golkov acting chief financial officer, effective Sept. 2, 2026, as John Markovich retires from the quantum computing company.
Golkov, who joined D-Wave in May 2023 as senior vice president of finance, will assume the roles of acting CFO and principal financial and accounting officer. His responsibilities will include oversight of accounting, SEC reporting, financial planning and analysis, treasury, and tax functions.
Markovich, who served as CFO for five years, oversaw the company’s capital raising efforts, which exceeded $900 million during his tenure. D-Wave noted that Markovich’s resignation was not related to any disagreement regarding business operations, accounting policies, financial statements, or internal controls.
Golkov brings more than 25 years of finance and accounting experience from publicly traded and private equity-backed technology companies. Prior to D-Wave, he held roles at Butterfly Network Inc. as vice president and controller from October 2020 to March 2023 and at Kaseya as senior vice president of finance from August 2018 to October 2020.
D-Wave Quantum, headquartered in Palo Alto, California, went public in 2022 and specializes in quantum computing systems, offering annealing and gate-model solutions alongside software and services delivered both on-premises and via cloud platforms.
