Deterministic Quantum-State Teleportation Achieved With High Fidelity
Teleportation, the transfer of quantum states between widely separated atoms, was achieved by different research teams in Austria and the United States.
(From Teleportation Setup)
...it has been shown that the entangling properties of quantum mechanics, in combination with classical communication, allow quantum-state teleportation to be performed. Teleportation using pairs of entangled photons has been demonstrated, but such techniques are probabalistic, requiring post-selection of measured photons. Here, we report deterministic quantum-state teleportation between a pair of trapped calcium ions. Following closely the original proposal, we create a highly entangled pair of ions and perform a complete Bell-state measurement involving one ion from this pair and a third source ion. Site reconstruction conditioned on this measurement is then performed on the other half of the entangled pair. The measured fidelity is 75%, demonstrating unequivocally the quantum nature of the process."
(From Deterministic Quantum-State Teleportation With Atoms)
For an early example of sf teleportation, see the transo from Clifford Simak's 1961 novel Time is the Simplest Thing. For an example of wireless communication at a distance (since quantum teleportation is really a transfer of information), see hyperwave relay from Isaac Asimov's classic Foundation, published in 1951.
