摘　　要：提出一种采用两组一般三粒子W态作为信道的传送两粒子任意态的方案.在此方案中,在发送者作Bell基测量后,接受者需要采用幺正变换和冯.诺依曼测量来实现传送方案.接受者可以选择在不同的粒子上恢复未知态,选择适当的幺正变换可使传态成功概率相等.A scheme for teleporting an unknown two-particle state is proposed when two general W states are utilized as quantum channels. After the sender＇s Bell-state measurements, the recipient needs to carry out appropriate unitary transformations and perform Von Neumann measurements. The recipient can realize teleportation with maximal probability of successful teleportation by selecting proper unitary transformations without considering on which particles to recover the original state.
