Quantum computers stand to revolutionize research by helping investigators solve certain problems exponentially faster than with conventional computers. Current quantum computers encounter a challenge ...

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 ...

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

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 ...

Quantum hardware has finally crossed a psychological threshold: it is no longer a science project in search of a purpose, it is a working tool that large companies and governments are starting to use.

Most simplifies the complex process of quantum computing as "it can be 0 and 1 at the same time." That is not an explanation ...

Much interest in quantum computer development was spurred by Peter Shor's 1994 discovery of an algorithm that showed how ...

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

Get the latest federal technology news delivered to your inbox. Quantum science, and especially its most popular offshoot, quantum computing, have come a long way in a fairly short period of time.

By adapting ideas from gauge theory, the researchers show how quantum information spread-out across a machine can be measured using only local checks, significantly lowering computing overhead. Their ...

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 ...
