(Phys.org)-Two Chinese teams working with quantum encryption and entanglement have achieved two more goals toward building a quantum space-based communication network. In the first experiment, one team succeeded in sending quantum keys from a satellite to two ground stations. In the second, another team sent entangled photons from the ground to a satellite. Both teams were made up of researchers from several institutions in China and both have published their results in the journal Nature.
