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 ...

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 ...

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 computers represent a breakthrough comparable to the move from valves to transistors in computer engineering. It doesn't just mean processing data faster; it means processing data in ways that ...

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 ...

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 ...

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 ...

Alexa von Tobel is fully aware that her big bet on quantum computing may never pay off. “The risk of being too early is a real risk,” she says. She’s speaking to me via Zoom from the New York City ...

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 ...

Taproot could be used to "hide" quantum safe spending conditions inside Bitcoin UTXOs to deal with the risk of quantum computing. Roughly a quarter of all Bitcoin is exposed to the risk of a quantum ...

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 ...
