摘要

An experimentally feasible scheme is proposed for the teleportation of an atomic state and of a two-atom entangled state within the microwave cavity quantum electrodynamics with unit probability of success. Our scheme is based on the interaction between atoms and a single-mode nonresonant cavity with the assistance of a strong classical driving field. Thus the teleportation. scheme is insensitive to the thermal state. This idea can also be used to teleport an arbitrary two-atom pure state via two pairs of atomic Einstein-Podolsky-Rosen states in a straightforward way.
