【摘要】 经典时钟同步方案易受色散和重力势效应的影响而出现较大误差。为此,文中提出了一种基于量子理论的时钟同步方案,该方案设备架构主要基于Mach-Zehnder干涉仪结构,通过两方互相发送光子并测量相位差以得到时钟差值。相较于经典方案,该方案在同步过程中不需要传递实体钟和测量脉冲抵达时间,因此不受重力势的影响。理论证明其抗色散影响,可以达到更高的精度要求。更多还原

【Abstract】 Aim.The introduction of full paper points out what we believe to be the shortcomings of two groups of references:(1)Refs.4 and 5;(2)Refs.7 through 13.Then it proposes our method of quantum clock synchronization using MZ interferometer,which we believe is better.Sections 1 and 2 present the results of our theoretical exploration.The title of section 1 is: our method of quantum clock optimization and its implementation;its core consists of:(1) Fig.2 shows the block diagram of our method of quantum clock synchronization;(2) subsection 1.2 gives a six-step procedure of implementation.The title of section 2 is:theoretical proofs;its core consists of:(1)subsection 2.1 gives the proof of our method;(2)subsection 2.2 gives the proof that our method suppresses dispersion greatly,thus allowing better precision to be attainable.更多还原
