"QUANTUM: Spooky entanglement demonstrated"

The National Institute of Standards and Technology (NIST) said it has demonstrated what it claims is the world's first entangled atoms that could be used to communicate information nondestructively. By creating multiple pairings of entangled atoms, NIST scientist Dietrich Leibfried was able to transmit quantum data and verify its reception from one pair without destroying the information in the other pair. Entanglement—referred to by Albert Einstein as "spooky action at a distance"—is a quantum phenomenon in which two particles—atoms or photons in close proximity—take on identical internal states. The synchronization, if conditions are right, can persist even if the particles are separated so that information processed by one pair is simultaneously processed by the other. Researchers believe the phenomenon could serve as the basis for enabling quantum computing capabilities
