A new room-temperature quantum device uses twisted light to entangle photons and electrons, overcoming one of the biggest hurdles in quantum technology. The breakthrough could pave the way for smaller ...

Digital secrets are protected by encryption, which converts meaningful data into an unintelligible form. If quantum computers ...

Deep inside a data centre in Manhattan, a quantum computer is enshrined in an alcove like an idol. To reach it, visitors pass two sets of sliding doors and banks of the conventional machines it is ...

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 ...

The U.S. government is investing in quantum computing. The interesting part is that this looks like a transition to a real quantum supply chain.
