| Abstract: | Microwave atomic clocks based on trapped ions have advantages in miniaturization and mobility. Therefore, they have attracted
widespread attention. Among them, the
113Cd
+
ion has become the main candidate ions for the new generation of practical ion microwave
clocks due to its advantages of low laser requirements and large ground-state hyperfine splitting frequency. In recent decades, multiple
experimental teams at home and abroad have conducted research on cadmium-ion microwave clocks. This article provides a detailed
introduction in chronological order of the technical routes and the latest developments adopted by different experimental teams at home
and abroad in the research of cadmium-ion microwave clocks. |
