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…
Evaluation of the systematic shifts of a optical clock
Kaifeng Cui, Sijia Chao, Chenglong Sun +7
Quantum-logic-based optical clock has been demonstrated in several schemes as there are different choices of the auxiliary ion species. In this paper, we pre…
Evaluation of blackbody radiation shift with temperature associated fractional uncertainty at 10E-18 level for 40Ca+ ion optical clock
Ping Zhang, Jian Cao, Hua-lin Shu +7
In this paper, blackbody radiation (BBR) temperature rise seen by the Ca ion confined in a miniature Paul trap and its uncertainty have been evaluated via finite-element…
A transportable 40Ca+ single-ion clock with systematic uncertainty
Jian Cao, Ping Zhang, Junjuan Shang +6
A transportable optical clock refer to the electric quadrupole transition at 729 nm of single trapped in mini Paul trap has been developed. Th…
