针对量子网络节点在复杂信道环境中可靠广播通信的问题,对其差错控制进行了研究,提出基于前向纠错差错控制的量子网络广播通信协议.在N+1个量子节点构成的网络中主量子节点向N个从量子节点广播量子信息,依据计算的误码数保留或删除在信息列表中从量子节点的信息,利用纠错码内在特性纠正保留从量子节点量子态的比特翻转和相位翻转错误,因为N个从量子节点测量基序列不同,纠错后N个从量子节点有不同的密钥,弥补了单个从节点泄密而造成整个网络泄密的不足.最后,在理论上分析了信道利用率及协议安全性.
Aiming at the problem that the quantum network node can reliably broadcast communication in complex channel environment, the error control is studied and a quantum network broadcast communication protocol based on forward error correction error control is proposed. In the network composed of N + 1 quantum nodes The quantum node broadcasts the quantum information to N slave quantum nodes, and retains or deletes the information from the quantum nodes in the information list according to the calculated number of errors, and preserves the bit inversion and phase inversion from the quantum node quantum states using the inherent characteristics of error correction codes Error, because N sub-nodes from different measurement base sequence, after the error correction from the N quantum nodes have different keys to make up for a single leak from the node caused by the leak of the entire network.Finally, the theoretical analysis of the channel utilization Rate and protocol security.
