摘　　要：提出一种较好的三粒子W态概率隐形传输方案,该方案用三个三量子比特W直积态作为量子通道。和闫等的方案相比,该方案提出一种新的正交完备测量基取代了以往所使用的Bell基测量。接收者根据发送者的测量结果实施适当的幺正变换操作,隐形传输成功的概率可以提高到20/27。A better scheme of probabilistic teleportation of a triplet W state is proposed, where the three three-qubit W states are taken as quantum channels. Compared with Yan＇s scheme, instead of using Bellstate measurement, a new orthogonal basis measurement is proposed in the scheme. The receiver performs appropriate unitary transformation according to the sender＇s measurements, the success of probabilistic teleportation can be improved to 20/27.
