It was experimentally realized only 4 years later, in 1997, by two independent research groups.
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. The basic principle behind quantum teleportation is entanglement (when two particles remain connected even when separated by vast distances).
