New research suggests quantum computers capable of breaking internet encryption may arrive sooner than expected—with AI ...

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 ...

The quantum layer will will not be exhausted by one hardware modality, one algorithmic framework or one vendor’s roadmap.

A team of physicists set out to test some of the most exciting claims in quantum computing—and found a very different story. Instead of confirming breakthroughs, their careful replication studies ...

Google's quantum paper made headlines with that number. Here's what it means, what's actually at risk, and why 6.9 million ...

A University of Sydney quantum physicist has developed a new approach to quantum error correction that could significantly ...

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 compact microwave-photon detector built from a semiconductor double quantum dot and a superconducting cavity could sharpen ...

Cisco signed a deal with Atom Computing to research the use of quantum networks to link neutral-atom quantum computers in ...

Chicago has quickly emerged as a hub for quantum computing, with the state of Illinois and technology companies pouring millions of dollars into developing a campus to build the world’s first ...
