Researchers report that they have designed and built a quantum computer from five atoms in an ion trap. The computer uses laser pulses to carry out Shor's algorithm on each atom, to correctly factor ...

Currently no commercially viable quantum computer exists. While a usable, functional quantum computer may exist in a few months, years, or even a few millenia (or a superposition of these states) we ...

Quantum computers could one day threaten the safety of the internet by breaking encryption – and now they are a step closer. A quantum computing start-up company called Zapata has worked with IBM to ...
