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 is the latest quantum computing company to say it has achieved “quantum supremacy,” better known as the ability to solve a problem with a quantum computer that can’t be done with a traditional computer.

D-Wave's claim that its quantum computers can solve problems that would take hundreds of years on classical machines have been undermined by two separate research groups showing that even an ordinary
