摘要/Abstract

摘要： 基于纠缠态作为信息载体的量子保密通信技术中，纠缠是其中的核心资源。如何保证通信中双光子态的纠缠度是量子保密通信的主要问题之一。研究了基于单模光纤的量子保密通信过程中的环境噪声，特别是电力架空光缆所处恶劣环境引入的噪声，可能导致量子纠缠退化的模型。分别从折射率的各向异性和吸收系数的各向异性讨论了环境噪声引起的量子纠缠横向退相干和纵向退相干效应。研究结果将对基于纠缠技术的量子保密通信在电力系统及其他恶劣电磁环境中的应用提供一定的参考。

Abstract: Entangled states are the core resources and the information carriers in private quantum communication technology. How to guarantee the entanglement of two-photon states is one of the main problems in quantum private communication. This paper studies the model of quantum entanglement degradation caused by ambient noise in quantum private communication technology based on single mode optical fibers, especially the noise of overhead power optical cables in the harsh environment. The transverse and longitudinal decoherence effects of quantum entanglement induced by ambient noise are discussed respectively from the anisotropy of refractive index and absorption coefficient. The research results will provide a reference for the application of entanglement-based quantum private communication in power system and other harsh electromagnetic environment.

Key words: power scenario, environment disturbance, quantum private communication, entangled state, entanglement degradation, information physics system
