Quantum teleportation was discovered by Charles H. Bennett (who coined the term) and Gilles Brassard in 1993.
These IBM scientists, making use of the EPR experiment, showed that it was physically possible to teleport objects at the atomic level. They showed that you could teleport all of the information contained within a particle.
Ever since this discovery, it has been shown that photons and even atoms (cesium and rubidium) can be teleported.
Quantum teleportation could have a theoretical explanation. The quantum information, which is the exact state of the particle, can be transmitted. This would involve entanglement between the sending and receiving locations. Two or more particles can be quantum entangled and could theoretically be moved from place to place.
It has been proven to be physically possible to transport qubits (unit of quantum information) between entangled particles.
However, the teleportation of humans raises ethical questions. This is because, the original copy, in quantum teleportation has to be destroyed. Despite an exact copy being produced of the teleporter, one would die in the process. Such teleportation may or may not be possible in the future. The answer is not yet clear.
