Scheme for teleportation of four-qubit cluster-class state in Cavity QED

本文提出了一个基于腔QED的隐形传送四比特团簇类态方案.在该方案中选用两个GHZ纠缠对作为量子通道.通过对原子和腔场的大失谐作用以及外加强经典场的辅助,可以制备纠缠的量子通道,完成联合的三粒子测量,成功地实现隐形传送四比特团簇类态.结果还表明,此方案不受腔场退相干和热场的影响.

We present a feasible scheme for teleportation of four-qubit cluster-class state in cavity OED. Two Greenherg-Horne-Zeilinger（GHZ） pairs are chosen as the quantum channel. By using the atom-cavity field interaction in the dispersive regime and with the assistance of a strong classical field,we can prepare the entangled quantum channel, accomplish the foint three-qubit measurement and then teleport the cluster-class state from the sender （Alice） to the Receiver（Bob） successfully. It is noted that this scheme is insensitive to both the cavity decay and the thermal field.
