本文分析了现有的量子密钥分配( quantumkeydistribution )实验系统并对实际实验系统的安全性给予了研究，最后给出了易于实现量子保密通信网络化的强衰减系统模型。 - Ideal single photon sources are far beyond real application . in practice , single photon sources being used are gained from precisely controlled heavy attenuation . to analyse the security of quantum key distribution system based on practical single photon sources is being very important
单光子是量子保密通信的一大技术关键，也是安全的基础，但是理想的单光子源离实际的使用还很远，目前实际使用的单光子源是由精密控制的强衰减技术得到的。 - The results show that thinner radar absorbing coatings can strongly attenuate high frequency surface waves , while alternate using of thin radar absorbing coatings and thin radar absorbing coatings compounded by frequency selective surfaces can strongly attenuate wideband surface wave and it is possible that high performance balanced stealth of super wideband can be reached using the alternate radar absorbing coatings
实验结果表明，低厚度的雷达吸波涂层就可以实现高频表面波的强衰减吸收，而频率选择表面与低厚度雷达吸波涂层相结合的复合涂层与雷达吸波涂层共同交替使用可以实现宽频段表面波的强衰减吸收，有望实现目标物体在宽频段范围内的高性能均衡雷达隐身。 - Practical implementations of quantum key distribution systems use attenuated laser pulses as the signal source rather than single photons . the channels used to transmit are lossy . on the basis of above two points , a combining eavesdropping strategy of intercept - resend and beam - splitting is discussed in terms of eavesdropper ' s technology requirement and detection efficiency and dark count of single - photon counter
主要工作包括以下三部分：一、基于实际量子密钥分配( qkd )系统中所使用的强衰减的激光脉冲不是单光子，量子密钥分配的信道不是无损耗的，光子计数器存在探测效率和暗计数以及窃听者的技术能力也不是无限的这些具体问题。 - Optical attenuation , widely applied in many fields , can be adopted to acquire single - photon sequence that is foundational in quantum key distribution . we obtain single - photon sequence by precisely controlled optical power distribution along outlets of manifold consist of beam splitter instead of the attenuation by time sequence due to loss
