| 摘 要： | 首先，针对传递三粒子w态的困难，提出了腔QED中的两种方案来完成w态的隐形传态．在一种方案中，我们利用一个EPR对和GHZ态来作为量子通道，在真空腔中实现了对w态的传送．而第二种方案与第一种不同之处是，我们使用了两个EPR对来作为量子通道，并且弓l入了一个附加粒子来完成传态的．此外，这些方案的显著优点是不用Bell基测量，而且可忽略腔场热作用和腔延迟作用的影响．

| Abstract: | We have investigated the problem of teleporting a three-atom entangled W state and propose two schemes based on entanglement swapping to complete the teleportation.We put forward the first scheme for the teleportation of W state by using an EPR pair and a GHZ state via vacuum cavities,the second scheme for teleporting W state by using two EPR pairs as quantum channels and introducing an addition atom via thermal cavities.Further more,the distinct advantage of the present schemes are that the Bell-state meas... |
