In the race to achieve quantum computing supremacy, a pure-play firm like D-Wave Quantum Inc. (NYSE: QBTS) must watch out for not only competitors of a similar size and scope but also for much larger ...

Quantum computing in 2026 still isn't a faster laptop. It doesn't make email snappier, and it won't speed up spreadsheets.

Quantum computers use qubits, which are based on quantum physics, allowing them to solve complex problems far faster than ...

One of the biggest promises of quantum computing is the ability to simulate molecules ...

But quantum computing uses “quantum bits,” also known as “qubits.” Instead of being either zero or one, qubits can behave like zero or one simultaneously and exist in states between zero and one, ...

Quantum computing could speed up AI training and inference once the technology matures. IBM's quantum computing track record spans decades, and the company has a clear and impressive quantum roadmap.

Paris-based quantum computing startup Alice & Bob has announced a stunning breakthrough in quantum computing: its qubits can now resist bit-flip errors for more than an hour. That’s four times longer ...

On May 7, 1981, influential physicist Richard Feynman gave a keynote speech at Caltech. Feynman opened his talk by politely rejecting the very notion of a keynote speech, instead saying that he had ...

So, Microsoft’s been working on something pretty big in the quantum computing world. They’ve developed this new ...
