摘　　要：基于超冷中性原子的光钟近年来发展迅速,将人类对时间频率测量的水平提高到了空前的高度。其中,超冷中性原子光钟的性能极大程度上取决于其量子参考体系的囚禁方案。本文介绍了超冷中性原子的光钟原理与性能评估,并详细介绍了不同量子参考体系囚禁方案如何影响系统的不确定度与稳定度。The optical clock based on ultracold neutral atoms has seen rapid development in recent years,pushing humanity’s horizontal capability for time and frequency measurements to unprecedented heights.Among them,the performance of the optical clock with ultracold neutral atoms is significantly dependent on the trapping scheme of its quantum reference system.This article will introduce the principles and performance evaluation of the optical clock with ultracold neutral atoms,and provide a detailed exploration of how different trapping schemes for the quantum reference system impact the system’s uncertainty and stability.
