摘要：

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 into n parts and the original quantum information can be sent to anyone of the n recipients with the other n-1 recipients' collaboration. In addition, we will give a suggestion to realize this scheme via QED cavity.
