| 摘 要： | 基于集体噪声的思想,构造一个两粒子无消相干子空间,进而提出了一个可抵抗旋转噪声的双向量子安全直接通信协议.消息分发者直接将一比特秘密信息编码到对应的相干保持态,接收者执行确定的测量来解码消息.此外,通过对一些常见攻击情形的分析,对协议的安全性进行简要的讨论.

| Abstract: | A two-way quantum secure direct communication protocol against a collective rotation noise is presented.The protocol encodes one logical bit in two-qubit noiseless states,and so it can function over a quantum channel subjected to collective rotation.Since there is no basis mismatch in the decoding process,the intrinsic high efficiency is achieved.Moreover,the security of the proposed protocol against some common attacks is analysed,which shows that it is secure in theory. |
