摘要:本文提出了两种基于超纠缠 Brown 态的双向可控量子隐形传态的方案。其中一种方
案是 Alice 和 Bob 在 Charlie 的协助下通过部分纠缠分析实现一个任意未知态和一个确定态
的全双工互换。另一种方案是实现任意未知态的半双工互换。通信两方在第三方控制下进行
通信,其安全性也由可靠的第三方保护。由于使用了超纠缠,本方案相对于传统的单光子方
案,能传送更多的信息量,节约了资源,提高了远距离量子通信能力。

Abstract: Two bilateral controlled quantum teleportation schemes based on hyperentanglement
Brown state are proposed in this paper. One realizes the duplex exchange of an arbitrary unknown
state and a certain state between Alice and Bob with the aid of the trusty Charlie via the partial
entanglement analysis. The other realizes the half-duplex exchange of arbitrary unknown states.
municate with each other under the control of the third party which guarantee the
security munication. Since hyperentanglement is used, paring with the traditional
single photon scheme,the proposed schemes obviously transport more information, save resources
and increase the channel capacity of long-distance munication.
