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