标题： Non-Standard Probabilistic Teleportation through Conventionally Non-Teleporting Channels

摘要： 一种非标准的量子隐形传态方案被提出，其中在通常无法实现隐形传态的信道中实现了概率性隐形传态。我们利用纠缠单态性将一个未知状态融入多体纠缠信道中，使得接收方部分与网络分离。随后，发送方在适当的测量基下执行局部测量为基础的隐形传态协议，这使得接收方获得一个未知状态，并通过局部幺正变换与要传送的状态相连。此过程在一些情况下成功，例如W态和其他非最大纠缠的四量子比特态，其中传统的基于测量的方法已经失败。还发现，在某些四粒子信道中，目前的程序不成功，尽管传统的方法工作良好。 显示英文摘要

摘要： A non-standard teleportation scheme is proposed, wherein probabilistic teleportation is achieved in conventionally non-teleporting channels. We make use of entanglement monogamy to incorporate an unknown state in a multipartite entangled channel, such that the receiver partially gets disentangled from the network. Subsequently, the sender performs local measurement based teleportation protocol in an appropriate measurement basis, which results with the receiver in the possession of an unknown state, connected by local unitary transformation with the state to be teleported. This procedure succeeds in a number of cases, like that of W and other non-maximally entangled four qubit states, where the conventional measurement based approach has failed. It is also found that in certain four particle channels, the present procedure does not succeed, although the conventional one works well.
