The breakthrough addresses concerns that powerful quantum computers could eventually crack encryption standards to leave vulnerable financial systems, government communications, health data and media.

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 ...

Quantum computing is moving from physics labs into real hardware, promising to attack problems that overwhelm even the fastest supercomputers. Among the boldest claims is that these machines could ...

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 ...

Researchers from the University of Waterloo's Faculty of Science and the Institute for Quantum Computing (IQC) are prioritizing collaboration over competition to advance quantum computer development ...

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 ...

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.” ...

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 ...

Software firm Horizon Quantum claimed it is the first private company to deploy a commercial quantum computer in Singapore. The deployment also makes it the first quantum software company to deploy ...

Google LLC’s quantum division today released research showing that its Willow quantum chip can provide elegant and accurate simulations about the physical properties of molecules much faster than ...

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 ...
