摘要:

根据多级分层量子信令网络的信令交换需要,提出了基于纠缠交换、局部幺正变换和量子隐形传态的量子信令直接传输方法.分析了量子信令损伤的因素以及修复策略,提出了量子信令传输损伤的概率模型(P模型).所提出的概率模型体现了非理想经典信道和噪声背景对信令的影响,计算性复杂度低.分析结果表明: 所提出的量子信令交换方法适合于多级量子信令网中信令传输的要求,对拦截-测量-转发、截获-替换、增加附属位等攻击具有很强的安全性.

Abstract:

A quantum signaling transmission scheme based on quantum entanglement, local unitary operation and teleportation is proposed for signaling transmission in a multiuser quantum signaling network with multi-stage hierarchy level network topology. The analytical result shows that the scheme is secure in case of eavesdropping attack including intercept-measure-resend attacks, intercept-replace and adding-ancilla attacks. Consequently, the probability model of quantum signaling transmission damage probability and the repair strategy of the damage of quantum signaling are presented, and the probability model in noise background and non-ideal traditional channel has very low complexity.

Key words: quantum communication, signaling transmission, quantum entanglement, teleportation, quantum secure direct communication
