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 ...

A small mathematical revision to quantum mechanics could effectively limit the purported infinite capacities of quantum ...

A technology leap comparable to the jump from vacuum tubes to integrated circuits has been achieved with the delivery of the first full-stack quantum computer built using a standard silicon CMOS chip ...

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 claims to have kicked off the “quantum-GPU computing era,” unveiling a way for quantum computers to interconnect with classical systems. Revealed at the chip giant’s GTC event in Washington, ...

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 ...

Scientists have unveiled a new approach to powering quantum computers using quantum batteries—a breakthrough that could make future computers faster, more reliable, and more energy efficient. Quantum ...

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 ...
