摘要：

We propose a protocol for teleporting an unknown coherent-state superposition within a network consisting of 2(N) parties with N an arbitrary positive integer. We show explicitly that for moderate and high intensity fields the probability of success is 50%, i.e. the same as in the case of N=1.
