Quantum optics

Push-button photon entanglement

Nature Photonics volume 8, pages 174–176 (2014)Cite this article

Subjects

A source of entangled photons that emits one — and only one — pair of photons on demand has now been realized in a semiconductor chip. The solid-state source will be a useful resource for experiments in optical quantum information.

Quantum entanglement, derided by Einstein as “spooky action at a distance,” is one of the most bizarre phenomena in the quantum world. In photonics, the ability to entangle photons has given laboratories an essential resource for processing quantum information.
