摘要:

研究了以非正交量子比特态为资源的量子隐形传态。我们首先扩展了标准的隐形传态协议的情况下,这样的国家。我们研究如何使用非正交态的隐形传态保真度的损失相比,一个类似的保真度损失时,噪声或非最大纠缠态作为隐形传态资源。我们的分析导致某些有趣的结果的隐形传态效率的纯和混合的非正交态相比,非最大纠缠和混合状态。

英文摘要:

We study quantum teleportation with the resource of non-orthogonal qubit states. We first extend the standard teleportation protocol to the case of such states. We investigate how the loss of teleportation fidelity resulting for the use of non-orthogonal states compares to a similar loss of fidelity when noisy or non-maximally entangled states as used as teleportation resource. Our analysis leads to certain interesting results on the teleportation efficiency of both pure and mixed non-orthgonal states compared to that of non-maximally entangled and mixed states.
