Quantum computing, on the cusp of a technological revolution, is set to significantly alter the way we process and interact with data. The latest quantum computer has implications far beyond the ...

There are currently about 80 companies across the world manufacturing quantum computing hardware. Because I report on quantum computing, I have had a chance to watch it grow as an industry from up ...

Quantum computing is one of those technologies where real-world applications always seem to lie just over the horizon. The next big thing is announced before quickly becoming a forgotten article from ...

A gold superconducting quantum computer hangs against a black background. Quantum computers, like the one shown here, could someday allow chemists to solve problems that classical computers can’t.

Quantum computers still can’t do much. Almost every time researchers have found something the high-tech machines should one day excel at, a classical algorithm comes along that can do it just as well ...

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 ...

For quantum computers to change the game of computation, scientists need to show that the machines’ calculations are correct. Now, there’s hope. Google’s Willow quantum chip has achieved verifiable ...

When a molecule absorbs light, it undergoes a whirlwind of quantum-mechanical transformations. Electrons jump between energy levels, atoms vibrate, and chemical bonds shift—all within millionths of a ...

QuamCore Ltd, a startup working to develop a quantum computer with one million qubits, today announced that it has raised $26 million in early-stage funding. Sentinel Global led the Series A round ...

The world of quantum computing has barged into a new frontier: space. A tiny quantum computer housed in a satellite is now in orbit around Earth, ScienceNews reports, residing some 330 miles above our ...

D-Wave, IonQ, and Rigetti use different approaches to build quantum computers. All three companies are unprofitable but are generating sales from their quantum systems. The odds are stacked against ...
