Laser pulses could power quantum logic gate. ... But he says it is “quite clear” the new design will operate differently and more efficiently that other designs of optical quantum computers.

In this work, the researchers used ions as their qubits. Rapidly oscillating electric fields trap the ions in a chain, making it possible to perform computational operations by shining laser light on ...

By clarifying the role of “real” and “virtual” charge carriers in laser-induced currents, researchers at Rochester and Erlangen have taken a decisive step toward creating ultrafast computers.

A new design for a laser that is powered by sunlight has been unveiled by researchers in Algeria and Portugal. The solar laser, which has yet to be built in the lab, is predicted to operate at a ...

Researchers have now developed the fastest logic gates ever created, by zapping graphene and gold with laser pulses. The new logic gates are a million times faster than those in existing computers ...
