Advancing optical clock performance with enhanced quantum control
Abstract
This research focuses on the development of quantum control techniques that will enhance lasercooling, optical trapping, and state coherence of atoms in optical lattice clocks. This enhancedquantum control will directly facilitate advances beyond the current state-of-the-art in opticalclock stability and accuracy, as well as improvements in the size and portability of optical clocksystems towards operation outside the laboratory environment. The implementation of thesequantum control techniques will culminate in the realization of an optical clock with instability at 1x10-17/ (for averaging time, ), and long term stability at 1x10-19 (in units of fractionalclock frequency). Furthermore, a two-color grating-magneto-optical-trap will be developed as acompact laser-cooled atom source. This will then be integrated into an existing optical latticeclock system, and characterized for deployment in a high-accuracy portable optical clock. Theresulting improvements in optical clock performance and portability can benefit high-precisionnaval timing applications.
