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 ...

Can quantum computing save us from 500 missiles attacking simultaneously? Perhaps ... and it has a far better shot than ...

A hundred years ago, quantum mechanics was a radical theory that baffled even the brightest minds. Today, it's the backbone of technologies that shape our lives, from lasers and microchips to quantum ...

Quantum hardware has finally crossed a psychological threshold: it is no longer a science project in search of a purpose, it is a working tool that large companies and governments are starting to use.

A gold superconducting quantum computer hangs against a black background. Quantum computers, like the one shown here, could someday allow chemists to solve problems that classical computers can’t.

IBM says quantum computing will be built on top of existing architecture, such as classical GPUs.

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 Connecticut nonprofit is on a mission to deliver educational programs to high school students in New Haven. District Arts ...
