中文摘要: |
量子通信过程中存在很多不理想因素(光子的制 备和获取,信道噪声的干扰等),同时受到实验条件的限制,利 用计算机对其进行模拟仿真是量子通信的一种重要的方法。针对以上问题,结合Matlab中强 大的矩阵运算功能和可视 化界面,设计了量子安全直接通讯(QSDC)协议的仿真程序。根据四粒子团簇态的变换公式, 提出了四粒子团簇态的制备算法和基于四粒子 团簇态的QSDC协议仿真算法,并模拟了其通信过程。仿真结果与理论结果相一致验证了协议 的安全性和正确性,也证 明了利用计算机对量子通信进行仿真的可行性。利用Action script(AS)代码实现量子通信 过程中一些不可观察的过程可视化。 |

In the actual quantum communication,there are many non-ideal factors and some l imitations of experimental condition.In order to solve the above problems,this paper combines the powerful matrix operation function and the visual interface of MATLAB,and then develops the simulation program of quantum secure direct communication (QSDC) protocol.In the light of the trans formation formula of the four particle cluster state,this paper puts forward the preparation algorithm of four particle cluster state and the quantum secure direct communication protocol simulation algorithm based on the four particle cluster state,and also simulates its communication process.The consistency between the experimental result and theoretical result shows the security and validity of th e protocol,and proves the feasibility of using computer to simulate the quantum communication as well.The AS code is used to make some u nobservable quantum communication progresses visualization and promote the further development of quantum communic ation. |
