给出了一种制备多原子特殊纠缠W类态的方案,该方案可用于精确传送任意未知的二能级二原子态。在这个过程中,量子信息被分割成多个部分,并且原始量子信息可以在其他n-1个接收者的协作下被发送给n个接收者中的任何一个。此外,我们还提出了利用QED腔实现该方案的建议。
We give a protocol to prepare specially entangled W-class state of multi-atom which can be used to exactly teleport an arbitrarily unknown two-level two-atom state. During the process, the quantum information is split intonparts and the original quantum information can be sent to anyone of thenrecipients with the othern-1 recipients’ collaboration. In addition, we will give a suggestion to realize this scheme via QED cavity.
