Just a few years ago, many researchers in quantum computing thought it would take several decades to develop machines that ...

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 ...

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 ...

After decades spent gestating in labs, quantum computing has finally reached an inflection point between theoretical promise and practical implementation. From discoveries in pharmaceutical and ...

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 ...

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

Researchers have found a way to make the chip design and manufacturing process much easier — by tapping into a hybrid blend of artificial intelligence and quantum computing. When you purchase through ...

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.

Trapped-ion quantum computing operates at room temperature, unlike other types that need extreme cold. This type of quantum computing is promising for stable, long-term research and application.

Quantum computing is moving from physics labs into real hardware, promising to attack problems that overwhelm even the fastest supercomputers. Among the boldest claims is that these machines could ...
