| 摘 要： | 我们提出一个利用腔QED技术控制传输任意两原子态的方案.在此方案中,我们选择一个GHZ态和一个EPR对作为量子通道.在控制者的帮助下,发送者可以把量子信息传送给接收者.在传输过程中,两对原子分别与两个全同单模场相互作用,同时两对原子分别由两个全同经典场驱动.该方案对腔衰变和热场不敏感,并且传输成功的几率为1.

| Abstract: | We propose a scheme for controlled teleportion of an arbitrary two-atom state in cavity QED. In the scheme a GHZ state and an EPR pair are chosen as quantum channels. The sender can teleport quantum information to the receiver with the help of the controller. In the teleportation process two pairs of atoms interact respectively with two identical single-mode cavities; meanwhile, the two pairs of atoms are respectively driven by two identical classical fields. The scheme is insensitive to the cavity decay and thermal field and the success probability is 1.0. |
