摘要/Abstract

摘要： 基于MATLAB图形用户界面接口（GUI），采用软件设计方式，实现量子纠缠光信号的采集，以及对采集到的两路量子纠缠光信号的符合算法。通过对符合算法中不同的符合门宽、采集时间和延时增加步长3个重要参数的性能实验，优化和确定各参数的选值。通过对量子纠缠光符合计数与到达时间差（TDOA）的研究，完成地面数据获取与信息处理模块的设计与实现。设计并实现了时间差拟合的仿真平台。实验结果达到了期望的精度和效率的需求。

Abstract: Based on the Graphic User Interface (GUI) in MATLAB, the software is designed to realize the acquisition of quantum entangled light signals and the coincidence algorithm of the two entangled photon signals collected. At the same time, the selection of each parameter is optimized and determined by performance experiments on three important parameters including the coincidence gate width, the acquisition time and the delay increasing step in the coincidence algorithm. The design and implementation of the ground data acquisition and information processing module is completed by studying coincidence counting and Time Difference of Arrival (TDOA) based on quantum entangled light. Finally, the simulation platform of TDOA fitting is designed and implemented. The experimental results meet the desired accuracy and efficiency requirements.

Key words: spontaneous parameter down conversion, quantum entangled light, Time Difference of Arrival (TDOA), coincidence counting, curve fitting
