    Project: ResearchEU project


    Optical clocks with 1 × 10-18 uncertainty are needed by a wide range of sectors from basic science and metrology to applications in geodesy, satellite navigation and environmental monitoring. This three year collaborative project aims to develop world-leading optical atomic clocks across Europe by addressing the following technical objectives:
    – To achieve instabilities in laser frequencies of 1 × 10-16 or below after 1s
    – To develop traps for single ions and neutral atoms that support > 1 s probe times
    – To evaluate and reduce systematic uncertainties in optical clocks to the level of 10-18
    – To implement novel interrogation methods with an optimised sequence of probe pulses
    – To validate the performance of optical clocks through direct frequency comparisons
