Quantum computers work by applying quantum operations, such as quantum gates, to delicate quantum states. Ideally, quantum ...

When Richard Feynman first conceived of quantum computers in the 1980s, he believed they should primarily investigate quantum phenomena. So that’s what a group of chemists did: they used quantum ...

An international team of scientists from IBM, The University of Manchester, Oxford University, ETH Zurich, EPFL and the University of Regensburg have created and characterized a molecule unlike any ...

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

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

Quantum computers are shifting from lab curiosities into real machines that can already outperform classical systems on narrow tasks, and the stakes are no longer theoretical. The technology promises ...

A team at IBM Research has assembled a strange new ring-shaped molecule that bends around like a more complicated Möbius strip ...

The JVG algorithm factors RSA and ECC keys using fewer quantum resources than Shor’s algorithm, accelerating the time needed ...

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