The basic principle behind quantum teleportation is entanglement (when two particles remain connected even when separated by vast distances).
Quantum teleportation was first investigated in 1993 by scientists who were using it as a way to send and receive quantum information. It was experimentally realized only 4 years later, in 1997, by two independent research groups.
