China to launch a "quantum satellite" in July 2016


The China's Quantum Experiments at Space Scale (QUESS) satellite, to be be launched in July 2016, will complete China's growing quantum communications network, which includes a 2,000-kilometer-long network between Beijing and Shanghai.

QUESS's function is to test the phenomena of quantum entanglement. Operated by the China Academy of Sciences, this 500kg satellite contains a quantum key communicator, quantum entanglement emitter, entanglement source, processing unit, and a laser communicator. QUESS will relay transmissions between two ground stations (one in China, and the other in Europe) transmitting quantum keys.
