摘要
利用Greenberger-Horne-Zeilinger态的纠缠特性,提出一个三方量子安全直接通信方案,参与者通过对Greenberger-Horne-Zeilinger态进行单粒子幺正操作,编码其一比特经典消息,最后每个参与者都可根据自身的秘密消息获得另外两个参与者发送的秘密消息。此外,对协议在理想情况下的安全性进行简要的分析,表明该协议是安全的。
The entanglement of Greenberger-Horne-Zeilinger state was used to present a three-party quantum secure direct communication protocol. In the protocol, one participant encodes a classical bit by performing single-particle unitary operation on Greenberger-Horne-Zeilinger state. At the end of the presented protocol, each participant obtained the secret messages transmitted by in an optimal situation was analyzed briefly. The result the other two participants. The security of this protocol showed that this protocol was secure.
