Abstract

一个控制的双向量秘密直接通讯计划被使用 Greenberger-Horne-Zeilinger (GHZ ) 建议状态。在计划，二个用户能在第三方的控制下面与一套设备同时交换他们的秘密消息。计划的 Thesecurity 被分析并且证实。

Controlled Bidirectional Quantum Direct Communication by Using a GHZ State

Man Zhong-Xiao, Yun‐Jie Xia

A controlled bidirectional quantum secret direct communication scheme is proposed by using a Greenberger–Horne–Zeilinger (GHZ) state. In the scheme, two users can exchange their secret messages simultaneously with a set of devices under the control of a third party. The security of the scheme is analysed and confirmed.

为安全直接通讯基于 Greenberger Horne Zeilinger (GHZ ) 说的三聚会的量的一个协议最近被 Jin 等建议。[Phys。Lett。一 354 (2006 ) 67 ] 由分析协议，我们发现某安全枪眼，没有任何偷听，例如一位一个聚会(在原来的纸的艾莉斯) 的秘密消息，罐头总是直接被漏到公众。以前建议的这些问题被讨论，可能的答案被介绍改进原来的协议的安全。

我们建议产生 Greenberger-Horne-Zeilinger (GHZ ) 的一个计划说，簇许多套住的离子说。在计划，离子被调节到第一条更低的震动的边带的单个激光照亮。计划仅仅要求反响的相互作用。Thusthe 计划很简单，量动力学操作能以高速度被认识到，鉴于 decoherence，它是重要的。

Improvement of Security of Three-Party Quantum Secure Direct Communication Based on GHZ States

Man Zhong-Xiao, Yun‐Jie Xia

A protocol for three-party quantum secure direct communication based on Greenberger–Horne–Zeilinger (GHZ) states was recently proposed by Jin et al. [Phys. Lett. A 354 (2006) 67] By analysing the protocol we find some security loopholes, e.g. one bit of secret messages of a party (Alice in the original paper) can always be leaked straight to the public without any eavesdropping. These problems suggested previously are discussed and possible solutions are presented to improve the security of the original protocol.

Complete hyperentangled Greenberger-Horne-Zeilinger state analysis for polarization and time-bin hyperentanglement

Zhi Zeng

We present an efficient scheme for the complete analysis of hyperentangled Greenberger–Horne–Zeilinger (GHZ) state in polarization and time-bin degrees of freedom with two steps. Firstly, the polarization GHZ state is distinguished completely and nondestructively, resorting to the controlled phase flip (CPF) gate constructed by the cavity-assisted interaction. Subsequently, the time-bin GHZ state is analyzed by using the preserved polarization entanglement. With the help of CPF gate and self-assisted mechanism, our scheme can be directly generalized to the complete N-photon hyperentangled GHZ state analysis, and it may have potential applications in the hyperentanglement-based quantum communication.
