【摘要】：针对多节点在局域网中的量子保密通信,建立了一种基于纠缠交换协议的令牌环局域网络传输模型。该模型结合纠缠交换协议,通过引入令牌环原理,进而使得量子无线基站可以在确定的时隙内分发纠缠资源给2个节点,进行无冲突通信。分析了网络的性能,推导得到了网络信息吞吐率与量子隐形传态成功概率和信道纠缠度之间的关系,通过MATLAB仿真实验对吞吐率的数值进行了分析,证明该模型的可行性,结果表明:提高通信双方建立纠缠资源、Bell态测量及成功接收测量信息的概率以及缩短信息的传输时间和优化信道的质量提高信道的纠缠度,可以增加网络的吞吐率,能有效满足量子通信的保密需求,对该领域的后续研究具有一定的参考价值。
[Abstract]:A token ring local area network transmission model based on entanglement switching protocol is established for the quantum secure communication of multi-nodes in LAN. The model combines the entanglement switching protocol and introduces the token ring principle. Then the quantum wireless base station can distribute entangled resources to two nodes in a fixed time slot for conflict free communication. The performance of the network is analyzed. The relationship between network throughput and quantum teleportation success probability and channel entanglement is derived. The numerical value of throughput is analyzed by MATLAB simulation, and the feasibility of the model is proved. The results show that the probability of establishing entangled resource Bell state measurement and successfully receiving measurement information is improved, the transmission time of information is shortened and the channel quality is optimized to improve the entanglement degree of the channel. It can increase the throughput of the network and meet the security requirements of quantum communication effectively. It has some reference value for the follow-up research in this field.

【正文快照】： 量子通信技术现如今正突飞猛进地发展[1-2],自1984年BB84协议[3]293提出以来,运用量子测不准原理和不可克隆定理[4]在理论上证明了量子密钥分发的安全性,但在实际中由于诸多环境因素的影响,加上相关技术尚未成熟,BB84协议并非绝对安全。因此研究者相继又提出了E91[5]、B92[6]
