Scientists at the Quantum Dynamics division of the Max Planck Institute of Quantum Optics (MPQ) in Garching, Germany announced Wednesday that they have built the very first, elementary quantum network comprised of a pair of entangled atoms that transmit information to each other via single photons. The network consists of two nodes, each of which can send, receive and store information, communicating via a single photon traveling along a 60-meter fiberoptic cable. "This approach to quantum ...
