Controlled teleportation of unknown atomic states using non-maximally entangled states

Abstract

Abstract:

A physical scheme for teleporting unknown atomic entangled states via three-atom non-maximally entangled states is proposed in cavity QED. The distinct advantage of the scheme is that, not only the teleportation and distillation procedure can be realized simultaneously, but also the scheme is insensitive to the cavity decay and thermal field with the assistance of a strong classical driving field. it is also unnecessary to concentrate non-maximally entanglement state quantum channel in advance. In addition, the joint Bell-state measurement can be distinguished via detecting the atomic state.

Key words: quantum optics, controlled teleportation, Cavity QED technique, a strong classical driving field, detuned interaction
