A research team at VTT MIKES has set a new record in optical-clock absolute frequency measurements using a strontium single-ion clock with exceptionally low uncertainty and high uptime. The official ...
In a new study, researchers carried out the most extensive coordinated comparison of optical clocks to date by operating clocks and the links connecting them simultaneously across six countries.
Bright idea Optical fibres are playing a crucial role in the comparison of optical clocks. (Courtesy: istock/morepixels) Atomic clocks are crucial to many modern technologies including satellite ...
Optical clocks of the National Institute of Information and Communications Technology (NICT, Japan) and LNE-SYRTE (Systemes de Reference Temps-Espace, Observatoire de Paris, Universite PSL, CNRS, ...
Scientists have generated a real-time signal of an accurate time scale by combining an optical lattice clock and a hydrogen maser. The signal generated in this optical-microwave hybrid system ...
