Tailoring teleportation to the quantum alphabet
arXiv:quant-ph/0205098 · doi:10.1103/PhysRevA.67.022313
Abstract
We introduce a refinement of the standard continuous variable teleportation measurement and displacement strategies. This refinement makes use of prior knowledge about the target state and the partial information carried by the classical channel when entanglement is non-maximal. This gives an improvement in the output quality of the protocol. The strategies we introduce could be used in current continuous variable teleportation experiments.
