Flatiron Institute Classical Algorithm Overturns D-Wave Quantum Supremacy Claim in Study Published in Science

Researchers at the Flatiron Institute and Boston University published a study in Science on May 21, 2026 demonstrating that a classical algorithm using 3D tensor networks and belief propagation can match the performance of D-Wave's 5,000-qubit Advantage2 quantum annealing processor. The work directly refutes a March 2025 quantum supremacy claim by D-Wave, showing that standard laptops and workstations can achieve the same results on the targeted physics problem. The finding reshapes the debate over what genuine advantages quantum computers offer over their classical counterparts.
