John Martinis has already revolutionised quantum computing twice. Now, he is working on another radical rethink of the ...

A new light-based breakthrough could help quantum computers finally scale up. Stanford researchers created miniature optical cavities that efficiently collect light from individual atoms, allowing ...

Quantum computing is nearing the point of practical use, but scientists still need to make some specific breakthroughs.

Simmons says that silicon quantum processors offer an inherent advantage in scaling, too. Generating numerous registers on a ...

Quantum computers are hungry machines, and their appetite is not just for qubits but for power delivered with exquisite ...

The day when quantum computers will be able to break conventional encryption is rapidly approaching, but not all companies ...

Quantum computers need extreme cold to work, but the very systems that keep them cold also create noise that can destroy fragile quantum information. Scientists in Sweden have now flipped that problem ...

A new way of capturing light from atoms could finally unlock ultra-powerful, million-qubit quantum computers. After decades of effort, researchers may finally be closing in on a practical path toward ...

IBM and Cisco are partnering on the groundwork for networked distributed quantum computing, to be realized as soon as the early 2030s. By combining IBM’s leadership in building useful quantum ...
