More reliable way to produce single photons

Physicists at the University of Bath have developed a technique to more reliably produce single photons that can be imprinted with quantum information.

Moving beyond semiconductors for next-generation electric switches

Computers use switches to perform calculations. A complex film with "quantum wells"—regions that allow electron motion in only two dimensions—can be used to make efficient switches for high-speed computers. For the first ...

An optical switch based on a single nano-diamond

A recent study led by researchers of the ICFO (Institute of Photonic Sciences) demonstrates that a single nano-diamond can be operated as an ultrafast single-emitter optical switch operating at room temperature. The scientific ...
