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

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

Using a superconducting quantum computer, physicists created a large and complex version of an odd quantum material that has ...

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.

Researchers at Academia Sinica have developed a 20-qubit superconducting quantum computer, marking Taiwan’s entry ...

Quantum technologies, devices and systems that process, store, detect, or transfer information leveraging quantum mechanical ...

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 ...

IBM is no longer talking about quantum computing as a distant science project. It is laying out a tightly sequenced plan that stretches from today’s noisy chips to fault-tolerant machines that could ...
