Teleportation of on N-particle GHZ state via one three-particle W state
利用一个三粒子W态隐形传送N粒子GHZ态

Recently Yang Hon-qin et al proposed a scheme for teleporting a three-particle GHZ state from a sender to either of two receivers with two three-particle W state quantum channel. In this paper, the theoretical analysis is given and the new scheme for teleporting an N- particle GHZ state using only one three-particle W state quantum channel is proposed.
