摘要 随着量子通信在近年来的不断发展, 量子安全直接通信成为了量子通信的一大重要分支。但目前的实验设备很难满足量子通信实验, 导致通信协议的正确性和安全性无法得到验证。针对这一问题, 提出了一种协议仿真算法。在Microsoft Visual C++6. 0平台上利用C++语言编写了量子安全直接通信协议的仿真程序, 最终实现了发送方和接收方之间的有效安全通信。仿真结果体现了量子通信的高效性和绝对安全性。实验结果与理论结果相吻合, 进一步验证了协议是安全、正确的, 也证明了用计算机对量子计算进行仿真的可行性。

英文摘要 With the development if quantum communication, quantum secure direct communication has become a very important branch of quantum communication. But the current experiment equipment is difficult to meet the quantum communication experiment, which leads to correctness and safety of the communication protocol cannot be verified. In order to solve this problem, this paper proposed a protocol simulation algorithm. In Microsoft Visual C++ 6. 0 platform using C++ language to write the simulation program of quantum secure direct communication protocol, finally achieved effective and safe communication between sender and receiver. Simulation result reflects the high efficiency and absolute security features of quantum communication, in addition, consistent with the theoretical results further verify the correctness of the proposed agreement, also proves the feasibility of quantum computing simulation with computers.
