Chinese Scientists Just Set the Record for the Farthest Quantum Teleportation

Chinese scientists have just shattered a record in teleportation. No, they haven't beamed

anyone up to a spaceship. Rather, they sent a packet of information from Tibet to a satellite in orbit, up to 870 miles (1,400 kilometers) above the Earth's surface. More specifically, the scientists beamed the quantum state of a photon (information about how it is polarized) into orbit. Not only did the team set a record for quantum teleportation distance, they also showed that one can build a practical system for long-distance quantum communications. Such a communication system would be impossible to eavesdrop on without alerting the users, which would make online communications much more secure.
