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 ...

Dr. Dominic Williamson, a University of Sydney quantum physicist, has developed a new approach to quantum error correction that could significantly reduce the number of physical qubits required to ...

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 ...

Building a utility-scale quantum computer that can crack one of the most vital cryptosystems—elliptic curves—doesn’t require ...

Quantum walks sound abstract, but they sit at the center of a very concrete race: who will harness quantum mechanics to solve problems that overwhelm today’s most powerful supercomputers. Instead of ...

The startup’s central idea to bring quantum computing to room temperature is even more outlandish than quantum itself: ...

What once took up the entire space of IBM’s early computer lab now fits on a chip. The question is how and when will the ...

Quantum computers are developing more quickly than expected – and so is the threat to our current computer security ...

Naoris Protocol says its blockchain network uses quantum-resistant cryptography, as the wider crypto industry prepares for ...
