【摘要】 本书基于纠缠双光子对的产生接收和符合计数拟合的整体工作过程,利用MATLAB图形用户界面接口(GUI)设计,实现了一个完整的到达时间差获取的仿真平台。该平台包括纠缠双光子对的特性显示,量子光的产生与接收过程显示,曲线拟合后二阶关联函数曲线图,以及测量到达时间差数值的显示。可以通过界面模块选择符合计数过程中三个不同参数的取值,进行多组参数组合下的实验仿真,可以实现从皮秒到微秒范围内到达时间差的数值拟合仿真实验。仿真实例表明本文设计的仿真平台可以实现良好的人机交互的效果,有助于人们对量子导航定位系统中最关键的到达时间差获取过程的直观理解。更多还原

【Abstract】 Based on the overall working process of generating and receiving entangled two-photon pair and fitting coincidence counting,a complete simulation platform for time difference of arrival acquisition is realized by using MATLAB graphical user interface(GUI)design.The platform includes the characteristic display of the entangled two-photon pair,the display of the quantum light generation and reception process,and the display of the second-order correlation function curve after the curve fitting and the measured value of time difference of arrival.The user can select the values of the three different parameters in the counting process through the interface module,and carry out the experimental simulation under the combination of multiple sets of parameters,which can realize the numerical fitting simulation experiment of the arrival time difference from picosecond to microsecond.The simulation example shows that the simulation platform designed in this paper can achieve good human-computer interaction effect and help people to have an intuitive understanding of the most critical time difference of arrival acquisition process.更多还原
