News: Entangled-Light Pair Stored in Atomic Memory

A new experiment bridges the old quantum trick of entanglement--the strange faster-than-light communication between particles--with the much newer technique of halting light dead in its tracks. Researchers report in Nature that they have successfully sent a pair of entangled states of light into separate corners of an ultracold atomic cloud, stored them there briefly, and then sent them back on their separate ways without completely destroying the quantum link in the process.
