High-Dimensional Quantum Encryption Performed in Real-World City Conditions for First Time


For the first time, researchers have sent a quantum-secured message containing more than one bit of information per photon through the air above a city. The demonstration showed that it could one day be practical to use high-capacity, free-space quantum communication to create a highly secure link between ground-based networks and satellites, a requirement for creating a global quantum encryption network.
Other scientists have already tried quantum communications with a satellite. In June a team of Chinese physicists reports that it sent eerily intertwined quantum particles from a satellite to ground stations separated by 1200 kilometers.
