| 摘 要： | 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.

| Abstract: | We present a feasible schemes for teleportation of four-qubit cluster-class state in cavity QED. 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 joint 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 . |
