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…
Demonstration of chronometric leveling using transportable optical clocks beyond laser coherence limit
Yi Yuan, Kaifeng Cui, Daoxin Liu +6
Optical clock network requires the establishment of optical frequency transmission link between multiple optical clocks, utilizing narrow linewidth lasers. Despite achieving link n…
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…
Sympathetic cooling of - ion pair crystal in a linear Paul trap
Jun-juan Shang, Kai-feng Cui, Jian Cao +3
The Al ion optical clock is one of the most attractive optical clocks due to its own advantages, such as low blackbody radiation shift at room temperature and insensitiv…
