Scientists say they’ve cracked a key challenge in scalable quantum hardware after generating an error-correcting, light-based qubit on a chip for the first time.

Quantum tunnelling — when a particle skips through a barrier that classical physics would forbid — happens faster when objects have less energy, find physicists who worked out a way to probe photons ...

Imagine a world where quantum computers can communicate across cities, countries, or even continents, exchanging information at lightning speed with unbreakable security. Researchers at the University ...
