Picture a quantum computer. Are you imagining an ordinary computer, but somehow just better? If so, that would be a mistake, because quantum computers are fundamentally different. They rely on exotic ...

In a laboratory in Broomfield, Colorado, 98 atoms are suspended in mid-air, held in place by electric fields and cooled to temperatures close to absolute zero. Each atom is far smaller than anything ...

The amount of quantum computing power needed to crack a common data encryption technique has been reduced tenfold. This makes the encryption method even more vulnerable to quantum computers, which may ...

Years before emails, internet banking, cloud servers and cryptocurrency wallets, two scientists devised a way to keep secrets perfectly safe and indecipherable to eavesdropping outsiders. Their 1984 ...

A major obstacle in the development of powerful quantum computers is the growing number of cables required to control a computer as the number of qubits increases. Researchers at Chalmers University ...

Bitcoin’s security relies on elliptic curve cryptography, a one-way mathematical function that makes deriving a private key from a public key effectively impossible for traditional computers. Shor’s ...

Quantum computers are often benchmarked by the number of quantum bits (qubits) they have, but a large collection of unreliable qubits is no more useful than a football team of unskilled players.

New research from Google's Quantum AI team suggests a future quantum computer could derive a bitcoin private key from a public key in about nine minutes, potentially allowing attackers to hijack ...

Do we need quantum computers to fully understand complex chemical reactions? A new result, decades in the making, shows the surprising power of ordinary “classical” machines. What Garnet Chan cares ...
