New research suggests that a quantum computer could crack a crucial cryptography method with just 10,000 qubits.

Quantum computers struggle with a major flaw: their information vanishes unpredictably. Scientists have now created a new method that can measure this loss over 100 times faster than before. By ...

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 ...

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

Quantum processors operate in environments engineered to eliminate nearly all external interference. That just might make ...

Founded by four leading physicists from the Weizmann Institute and Technion, Q-Factor is developing neutral atom technology to break through quantum computing's scaling barriers TEL AVIV, Israel, ...

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 ...

(CNN) — 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.

Future quantum computers will need to be less powerful than we thought to threaten the security of encrypted messages.

Podcast and YouTube channel, The Quantum Kid, has been named as a 2026 nominee for Webby Awards People’s Choice award ...

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 ...
