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 ...

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

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 ...

Building a utility-scale quantum computer that can crack one of the most vital cryptosystems—elliptic curves—doesn’t require ...

A first wave of stocks at the start of the decade — comprising IonQ, Rigetti and D-Wave — highlighted the most mature quantum ...

Silicon is ubiquitous in modern electronics, and now it is becoming increasingly useful in quantum computing. In particular, ...

The Wisconsin Union Directorate welcomed renowned quantum physicist John Martinis to Shannon Hall on March 23 as part of the ...

Quantum computing’s threat to encryption is - conceptually at least – very simple. One day, perhaps quite soon, a quantum computer may be able to ...

Researchers have developed a tiny device that extinguishes one of the biggest heat sources in quantum computers, cutting their running costs and potentially bringing these machines closer to ...
