Braunstein and Kimble observe correctly that, in the Innsbruck experiment, one does not always observe a teleported photon conditioned on a coincidence recording at the Bell-state analyser. In their opinion, this affects the fidelity of the experiment, but we believe, in contrast, that it has no significance, and that when a teleported photon appears, it has all the properties required by the t...
متن کاملEnsemble Teleportation
The possibility of teleportation is by sure the most interesting consequence of quantum non-separability. So far, however, teleportation schemes have been formulated by use of state vectors and considering individual entities only. In the present article the feasibility of teleportation is examined on the basis of the rigorous ensemble interpretation of quantum mechanics (not to be confused wit...

DATA TYPE See DATA ABSTRACTION ABSTRACTION (The result of) a process of simplification, to describe something at a more general level than the level of detail seen from another point of view. This is often achieved by omitting details specific to individual cases or to methods of implementation. For example, a realtor’s description of a house may leave out architectural detail so that it is an ...
متن کاملQuantum teleportation.
For continuous variable systems, some protocols for entanglement swapping, establishing entanglement between distant stations through teleportation, testing the efficiency of teleportation with the aid of a third party, and combining teleportation with cloning have been proposed. But no protocol for the explicit teleportation of an entangled continuous variable state exists in the literature, a...
متن کاملBroadband teleportation
Quantum teleportation of an unknown broadband electromagnetic field is investigated. The continuousvariable teleportation protocol by Braunstein and Kimble @Phys. Rev. Lett. 80, 869 ~1998!# for teleporting the quantum state of a single mode of the electromagnetic field is generalized for the case of a multimode field with finite bandwith. We discuss criteria for continuous-variable teleportatio...
