July 3, 2020 William Bowden from NPL recently gave a virtual talk at UMK. Entitled “Strontium optical lattice clocks at NPL”, this covered a recent measurement of the absolute frequency of the Sr clock transition as well as the work being carried out within the ROCIT project to improve the reliability of the system. William also presented recent progress towards realising entangled states for enhanced clock performance. A recording of the talk is available on the project outputs page.
