Quantum walks sound abstract, but they sit at the center of a very concrete race: who will harness quantum mechanics to solve problems that overwhelm today’s most powerful supercomputers. Instead of ...

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 ...

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 ...

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 ...

The amount of quantum computing power needed to crack a common data encryption technique has been reduced tenfold. This makes the encryption method even more vulnerable to quantum computers, which may ...

Last year Universal Quantum, the quantum computing firm spun out of Sussex University, announced it was collaborating with the Open Quantum Institute (OQI) on using quantum computing in drug discovery ...

Rice University quantum computing researchers have introduced a novel algorithm with the potential to speed up quantum computing. This algorithm landed the team in the finals for the XPRIZE Quantum ...

Years before emails, internet banking, cloud servers and cryptocurrency wallets, two scientists devised a way to keep secrets perfectly safe and indecipherable to eavesdropping outsiders. Their 1984 ...
