摘要/Abstract

摘要：

提出一种较好的三粒子W态概率隐形传输方案，该方案用三个三粒子W直积态作为量子通道。和闫等人的方案相比，该方案具有以下的优点：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。

Abstract:

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, Our scheme have follow advantages: Instead of using Bell-state measurement, a new orthogonal basis measurement is proposed, the receiver performs appropriate unitary transformation according to the sender’s measurements, the success of probabilistic teleportation can improve to 20/27.

Key words: quantum optical, quantum controlled teleportation, three-qubit W state, non-Bell-state measurement
