Imagine shining a flashlight across a dark room. You can predict exactly what the light will do: travel in a straight line ...

Quantum circuits are supposed to gain power as they grow longer, but noise changes the picture. A new study finds that earlier steps in these circuits gradually lose their impact, with only the final ...

Last week, cybersecurity researchers woke up to bad news. Research in new papers published by Google and a quantum computing startup, Oratomic, suggests that quantum computers capable of breaking the ...

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 ...

Quantum computing promises a new generation of computers capable of solving problems hundreds of millions of times more quickly than today’s fastest supercomputers. This is done by harnessing spooky ...

Quantum computing has long felt like a perpetual promise — a mysteriously powerful technology that’s always “about 10 years away.” If you tuned it out, you weren’t alone. But something has shifted ...

Quantum computers might eventually be able to handle some AI applications that currently require huge amounts of conventional computing power. Such a development would be a major boost to machine ...
