Performing complex algorithms on quantum computers will eventually require access to tens of thousands of hardware qubits. For most of the technologies being developed, this creates a problem: It’s ...

Fusion energy has always had a tritium problem. The fuel that powers every leading reactor design barely exists on Earth in usable quantities, and the best candidate for breeding it inside a reactor — ...

Explore the potential of quantum computing and the challenges ahead as researchers strive to overcome noise and errors.

Quantum computers still face limits when it comes to storing information. Researchers at ETH Zurich are now turning to ...

This article is part of a package on the future of quantum computing. Read about the most promising applications of these machines here and see an illustrated field guide to qubits here. Inside a ...

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 ...

On May 7, 1981, influential physicist Richard Feynman gave a keynote speech at Caltech. Feynman opened his talk by politely rejecting the very notion of a keynote speech, instead saying that he had ...

Chinese researchers have developed a programmable quantum computing prototype that solved a complex mathematical problem faster than conventional supercomputers. The breakthrough manipulated thousands ...
