摘要
采用偏振和纵向动量耦合对单光子进行高维量子编码,使光子能够携带2比特信息且仅受到单边信道衰减。仿真结果表明,与传统2维协议相比,该协议的安全码率提升近1个数量级,并且能够突破无中继密钥率传输距离的限制,同时量子比特误码率仅为0.04。该解决方案显著提高了无线公网电力系统的安全性,为可靠的电力传输和数据通信提供了新的选择。
In order to improve the security of wireless public power systems,a solution based on high-dimensional twin-field quantum key distribution is proposed in this study.The scheme employs polarization and longitudinal momentum coupling for high-dimensional quantum coding of a single photon,which enables the photon to carry 2-bits of information and is subject to only one-sided channel attenuation.Simulation results show that compared with the traditional two-dimensional protocol,the security code rate of this protocol is improved by nearly an order of magnitude.Additionally,it has the capability to surpass the transmission distance limitations imposed by relay-free key rates,while the quantum bit error rate is only 0.04.This solution significantly improves the security of the wireless public power system,and provides a new option for reliable power transmission and data communication.
