Quantum walks sound abstract, but they sit at the center of a very concrete race: who will harness quantum mechanics to solve ...

What I am looking at is not just the most powerful computer in the world, but the key to financial security, Bitcoin, ...

Like their conventional counterparts, quantum computers can also break down. They can sometimes lose the atoms they manipulate to function, which can stop calculations dead in their tracks. But ...

NVIDIA isn’t building quantum computers, instead it’s using its supercomputing strengths to accelerate quantum computing ...

Physicist Jay Gambetta, at IBM’s lab in Yorktown Heights, New York, explains how microwaves orchestrate a solution on a quantum chip: “Think of each qubit as a line in music. You’re creating notes.” ...

What is it about quantum computers that makes them more powerful than conventional machines? A new experiment shows that the property of “quantum contextuality” may be a key ingredient. Quantum ...

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 ...

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 ...

Designed to accelerate advances in medicine and other fields, the tech giant’s quantum algorithm runs 13,000 times as fast as software written for a traditional supercomputer. A quantum computer at ...

London-based Quantum Motion Technologies Ltd. announced today it has delivered the industry’s first quantum computer built using traditional semiconductor chipmaking processes, the same technology ...

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 ...
