In a timely fashion, a day before its Q4 earnings report, D-Wave Quantum Inc. (QBTS) has proved its quantum computer can solve a real-world

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.

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

Wave Quantum Inc. (NYSE: QBTS) ("D-Wave" or the "Company"), a leader in quantum computing systems, software, and services and the world’s first commercial supplier of quantum computers, today announced a scientific breakthrough published in the esteemed journal Science,

Shares of some quantum computing companies rallied on Thursday, adding to gains from the previous session and bucking the broader market's trend after D-Wave Quantum forecast stronger-than-expected quarterly revenue.

Key Takeaways D-Wave and other quantum computing stocks soared Wednesday after the company claimed to achieve a breakthrough.D-Wave said its quantum computer outperformed one of the world's most powerful classical supercomputers.

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.
