Atomic teleportation via cavity QED and position measurements: efficiency analysis

摘要

We have recently presented a novel protocol to teleport an unknownudatomic state via cavity QED and position measurements. Here, after a brief reviewudof our scheme, we provide a quantitative study of its efficiency. This is accomplishedudby an explicit description of the measurement process that allows us toudderive the fidelity with respect to the atomic internal state to be teleported
