本文提出一种使用纠缠态实现的高效、安全的双向异步量子安全直接通信协议。利用诱骗光子检查窃听,这种协议的安全性等同于BB84协议。在确保量子信道的安全性之后,双方各自使用受控非门操作和局部幺正操作对加密信息编码。利用贝尔测量和冯·诺伊曼测量,与传统通信相结合,可实现双向异步秘密保密消息的直接传输。与目前的量子安全直接通信协议的不同,通信双方通过不同的操作对加密消息编码,这相当于两个非对称量子通道共享,该协议是安全的噪声量子协议。该协议有效应用于利用纠缠态来传递加密消息。 This paper presents an efficient and safe two-way asynchronous quantum secure direct communication protocol using entangled states. Using decoy photons to detect eavesdropping, the security of this protocol is equivalent to the BB84 protocol. After securing the quantum channel, both sides each use a controlled non-gate operation and a local unitary operation to encode the encrypted information. Using Bell measurements and von Neumann measurements, combined with traditional communications, direct bidirectional asymmetric secret messages can be transmitted. In contrast to current quantum secure direct communication protocols, both parties to the communication encode encrypted messages by different operations, which is equivalent to sharing two asymmetric quantum channels, which is a secure noise quantum protocol. This protocol is effectively used to deliver encrypted messages using entangled states.
