摘要：
We propose a scheme for tripartite entanglement swapping of continuous variables, where one EPR pair and one local W-type entangled state are utilized. Because of the co-existence of both bipartite and tripartite entanglement in a W-type entangled state, one optical beams of the EPR state will be entangled with the output modes displaced by Bob and Claire. Actually, the entanglement swapping processing could be viewed as teleclone of entangled state of continuous variables.
