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.
The experiment takes advantage of one of several phenomena that describes quantum mechanics: entanglement, or “spooky action at a distance,” as Albert Einstein called it. When two particles are entangled, they remain connected so that an action performed on one affects the other as well, no matter how far apart the two are.
