D-Wave’s fresh claim that it has achieved “quantum advantage” has sparked criticism of the company—and of the scientific process itself

D-Wave Quantum Inc. said today a peer-reviewed scientific paper proves it has finally passed a critical threshold and achieved “quantum supremacy” — that is, the point at which its quantum computers have finally solved a problem that’s impossible for even the most powerful “classical” computers to do.

The company says it has solved the first problem of scientific relevance with a quantum processor faster than it would be done with classical computers.
