Two scientists just won computing's Nobel Prize for an idea from 1984: use quantum mechanics to make eavesdropping physically ...

A small mathematical revision to quantum mechanics could effectively limit the purported infinite capacities of quantum computers—if validated, that is.

Quantum cryptography poses two questions for higher education technology leaders: What matters now, and what will matter decades from now? These questions are inseparable because quantum computers of ...

Cryptography pioneers Charles Bennett (left) and Gilles Brassard introduced the BB84 protocol the uses the principles of ...

Researchers say their prototype is a big step towards fully functioning batteries with rapid charging times ...

The pair will share the $1 million prize for their pioneering work in quantum cryptography and the broader field of quantum information science. Their 1984 paper ...

The rules of quantum mechanics describe how atoms and molecules act very differently from the world around us. Scientists have made progress toward teasing out these rules—essential for finding ways ...

A quantum internet is only as useful as its reach, and in a first, researchers created more than a million qubit pairs across 100 kilometers of fiber.

Quantum mechanics is both the most powerful theory physicists have ever devised and the most baffling. On the one hand, countless experiments have confirmed its predictions; the theory undergirds ...

The achievement marks the first time scientists have built a device that can be charged, store energy, and release it again ...
