Quantum computing is moving from physics labs into real hardware, promising to attack problems that overwhelm even the fastest supercomputers. Among the boldest claims is that these machines could ...

When we measure a qubit in superposition, it picks one state, like a spinning coin landing heads or tails. This is called ...

Quantum computers have become the latest canvas for humanity’s oldest fantasy: escaping death. Startups, futurists, and speculative essays now suggest that machines built to manipulate qubits could ...

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 ...

Quantum hardware and software are advancing rapidly – and our online encryption systems need to change to stay ahead.

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

You might think that creating a highly accurate model of the way air passes through a jet engine would be relatively easy. It is incredibly hard. The enormous number of variables means that it is, in ...

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 ...

Google quantum pioneer says encryption-breaking use cases may arrive sooner than expected, urging crypto industry to prepare now ...

Quantum computers could help explain some of the most fundamental mysteries in the universe and upend everything from finance to encryption—if only someone could get them to work.
