| 摘 要： | 提出一个在腔QED中实现特殊三粒子W态的隐形传送方案.在方案中用3个二粒子纠缠态作为量子通道,通过原子与腔及经典场之间的相互作用以及适当的幺正变换,以成功几率1实现了特殊三粒子W态的传送.此外,本方案不需要联合贝尔测量,对腔衰减和热场也不敏感.

| Abstract: | We proposed a scheme for teleporting a three-atom entangled W state in cavity QED.In the scheme,three EPR pairs are chosen as quantum channel shared by the sender and the receiver.By using atom-cavity-field interaction and appropriate unitary transformations,the three-atom entangled W state can be teleported successfully with probability 1.0.Moreover,the scheme does not need joint Bell measurement and is insensitive to the cavity decay and thermal field. |
