Teleporting Superposition of Even and Odd Coherent States of Cavity Field through the Interaction of V-type Three-Level Atom with the Cavity-field

实现腔场奇偶相干叠加态的隐形传送,在量子信息领域有非常重要的作用.提出利用V型原子与腔场的相互作用系统进行概率传送腔场的奇偶相干叠加态的有效方案.在此方案中,对于振幅很大的单模光场,通过实行Bell态测量,能成功地传送腔场的奇偶相干叠加态,其成功的总概率为0.25.

Realizing the teleportation of superposition of even and odd coherent states of cavity field is of great importance in quantum information. A feasible scheme is proposed to probabilistically teleport superposition of even and odd coherent states of the cavity field by the interaction of V-type three-level atom with the cavity-field of large amplitude under a far-off resonant condition. In this scheme, by performing Bell state measurement, the superposition of even and odd coherent states of the cavity field can be successfully achieved with a total probability of 0.25.
