Broadband 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...
متن کاملExperimental demonstration of quantum teleportation of broadband squeezing.
We demonstrate an unconditional high-fidelity teleporter capable of preserving the broadband entanglement in an optical squeezed state. In particular, we teleport a squeezed state of light and observe -0.8+/-0.2 dB of squeezing in the teleported (output) state. We show that the squeezing criterion translates directly into a sufficient criterion for entanglement of the upper and lower sidebands ...
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...
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 کاملQuantum Teleportation
Teleportation the transmission and reconstruction of objects over arbitrary distances is a spectacular process, which actually has been invented by science fiction authors some decades ago. Unbelievable as it seems in 1993 a theoretical scheme has been found by Charles Bennett et al. that predicts the existence of teleportation in reality at least for quantum systems. This scheme exploits some ...
