Enhancing the performance of differential optical clock comparisons using entangled state
Abstract
We propose to introduce Rydberg interactions into an existing multiplexed optical lattice clock apparatus for the generation of highly entangled quantum states. Differential measurements between the two atom ensembles in our apparatus will be immune to frequency noise of the shared clock laser and to common mode environmental perturbations, enabling record differential stabilities. The use of highly entangled states for quantum enhanced metrology in our apparatus can be expected to offer initial sensitivity enhancements by a factor of 2, offering record differential stabilities approaching the level of 2:5 10ÀÀ18= p . The proposed research is of direct relevance to the interests of the ARO AMP program through the potential impacts of novel quantum metrology with entangled states on precision navigation and timing, secure communications, and imaging and detection capabilities.
