Prospects for quantum enhanced measurements using Rydberg interactions in a multiplexed optical lattice clock
Abstract
We will investigate the prospects for harnessing Rydberg interactions for the generation of highly entangled quantum states in a multiplexed optical lattice clock (OLC), an apparatus with the capability of independent loading, preparation, and probing of 87Sr in two spatially separated, movable optical lattices with flexible geometries. Differential measurements between the atom ensembles in the two lattices will be immune to frequency noise of the shared clock laser and to common mode environmental pertubations, enabling record differential stabilities. The use of highly entangled states for quantum enhanced metrology can be expected to offer additional gains of more than an order of magnitude, promising differential stabilities approaching the "10^-19/the sq root of tau" level. We will investigate the prospects, optimal techniques, and hardware required for utilizing Rydberg interactions to generate highly entangled states in a multiplexed OLC, as well as the most likely challenges of implementation.
