D-Wave Quantum Inc. Response to Claims of Overturned Quantum Supremacy

D-Wave Quantum Inc. issued a response on May 26, 2026, addressing claims that recent classical simulation work has overturned their demonstration of quantum computational supremacy in quantum simulation. The company asserts that these claims are inaccurate and not supported by the scientific record. D-Wave acknowledges advances in classical methods, including recent work from the Flatiron Institute, but states that this work does not reproduce the full scope of D-Wave's peer-reviewed results, nor does it address the most challenging problem instances and measurements. CEO Dr. Alan Baratz emphasized that D-Wave's demonstration of beyond-classical computation continues to hold up under scientific scrutiny, welcoming progress in classical methods while refuting claims that they invalidate D-Wave's findings. The company welcomes continued work in classical simulation but stresses the importance of accurate scientific communication regarding the distinction between advancements in classical methods and the overturning of quantum supremacy results.
