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 ...

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 ...

What if the most complex problems plaguing industries today—curing diseases, optimizing global supply chains, or even securing digital communication—could be solved in a fraction of the time it takes ...

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 computers of the future may be closer to reality thanks to new research from Caltech and Oratomic, a Caltech-linked start-up company. Theorists and experimentalists teamed up to develop a new ...

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.
