China's Top 10 Optical Breakthroughs:Ultracold Neutral Atomic Optical Clock and Its Quantum Reference Trapping Scheme(Invited)
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.
