A new ultra-fast monitoring system reveals that quantum computer qubits can change from stable to unstable in mere milliseconds.

Quantum computing technology is complex, getting off the ground and maturing. There is promise of things to come. potentially ...

The breakthrough addresses concerns that powerful quantum computers could eventually crack encryption standards to leave vulnerable financial systems, government communications, health data and media.

The commonly used RSA encryption algorithm can now be cracked by a quantum computer with only 100,000 qubits, but the technical challenges to building such a machine remain numerous ...

Scientists in Switzerland have developed a new method to improve internet security against quantum computing attacks, using ...

Computer scientist Peter Gutmann tells The Reg why it's 'bollocks' The US National Institute for Standards and Technology (NIST) has been pushing for the development of post-quantum cryptographic ...

New evidence suggests a rare triplet superconductor may help quantum computers stay in sync by preserving electron spin ...

Quantum computers need special materials called topological superconductors—but they’ve been notoriously difficult to create. Researchers have now shown they can trigger this exotic state by subtly ...

Scientists built a quantum gate linking four-state photons, showing complex quantum tasks can be done with fewer steps using qudits.

The truth is that even the most optimistic vendor estimates for this would put very nascent stages of enterprise value toward ...
