Announcements about quantum computers are multiplying, yet this technology is still in its infancy, comparable to the era ...

Japan has switched on the first quantum computer that has been designed and built with components from the country. The system is now ready to take on workloads from its base at the University of ...

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 ...

A vital ingredient for making quantum computers truly useful just might be conventional computers. That was the message from a gathering of researchers this month, which explained that classical ...

A new paper published in Nature Communications could put scientists on the path to understanding one of the wildest, hottest, and most densely packed places in the universe: a neutron star. Christine ...

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 ...

In a major step toward practical quantum computers, Princeton engineers have built a superconducting qubit that lasts three times longer than today’s best versions. “The real challenge, the thing that ...

Researchers created scalable quantum circuits capable of simulating fundamental nuclear physics on more than 100 qubits. These circuits efficiently prepare complex initial states that classical ...

Quantum computers have performed the full slate of tricks needed for robust computation. And it all came down to a little magic. In a pair of papers submitted June 17 at arXiv.org, researchers ...

Quantinuum has unveiled a third-generation quantum computer that could be easier to scale up than rival approaches. The US- and UK-based company Quantinuum today unveiled Helios, its third-generation ...
