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.

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.

The Advantage2 computer that was used to achieve today’s milestone is available for customers today on D-Wave’s Leap real-time quantum cloud service. In addition, the very latest model of the Advantage2 is four times larger than the one used to demonstrate quantum supremacy.

Quantum computing firm D-Wave claims it has demonstrated quantum supremacy on a “useful, real-world problem.” The company said the achievement was made using D-Wave’s Advantage2 prototype annealing quantum computer. Quantum supremacy is when a quantum computer can carry out calculations that classical computers practically cannot.

The company says it has solved the first problem of scientific relevance with a quantum processor faster than could be done with classical computers—but others disagree

D-Wave Quantum (QBTS) said it has achieved "quantum computational supremacy" by being the first company to achieve real-world results with its annealing quantum computer.

The quantum computing firm is announcing what it describes as a major breakthrough, the results of which were published in the journal ‘Science.’ D-Wave is about to make waves.

D-Wave Quantum Inc., a California-based startup working in the realm of quantum computing for commercial applications, has solved a real-world useful problem using its D-Wave Advantage 2 prototype annealing quantum computer.
