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.
