基于Greenberger-Horne-Zeilinger态的控制量子安全直接通讯(英文)

Controlled Quantum Secure Direct Communication Based on Greenberger-Horne-Zeilinger States

我们利用Greenberger-Horne-Zeilinger(GHZ)态,提出了一个控制量子安全直接通讯方案。在方案中,我们不仅分析了这个方案的安全性,而且指出了这个方案可以有效地抵御截取再发送袭击和干扰袭击。

The paper presents a controlled quantum secure direct communication scheme by using Greenberger- Horne-Zeilinger （GHZ） states. The security of the scheme is analyzed and the results show that the scheme can efficiently resist the intercept-and-resent attack and the disturbance attack.
