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 computing is an emerging field that uses the principles of quantum mechanics to perform computation. A quantum computer is a very different type of computer that uses the weird rule of quantum ...

Charles H. Bennett and Gilles Brassard, winners of this year’s Turing Award, spent their lives touting the advantages of the ...

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 ...

Light moving through a tiny silicon structure does not look dramatic. It slips down narrow waveguides etched onto a chip, ...

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 ...

Researchers at the University of Massachusetts Amherst have built a chip-scale laser stable enough to control a trapped-ion ...

Governments and technology companies are fueling an urgent, high-stakes race to develop quantum power, which promises to revolutionize- and potentially compromise - global security Quantum computing ...

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 ...
