First GNSS-deployed optical clock for local time scale upgrade

Yi Yuan, Jian Cao, Jinbo Yuan +14

Precise time scale is the universal base for all measurements. Here we report the deployment of a compact and transportable optical clock to a timekeeping institution and steering…

Towards a compact transportable optical clock based on the octupole transition in 171Yb+

Xuanjian Wang, Jian Cao, Hualin Shu +5

Optical clocks have extremely attractive applications in many fields, including time-frequency metrology, validation of fundamental physical principles, and relativistic geodesy. T…

Evaluation of the systematic shifts of a $^{40} Ca^{+} -^{27} Al^{+}$ optical clock

Kaifeng Cui, Sijia Chao, Chenglong Sun +7

Quantum-logic-based $^{27} Al^{+}$ optical clock has been demonstrated in several schemes as there are different choices of the auxiliary ion species. In this paper, we pre…
