Spin squeezing of a Bose-Einstein condensate via quantum nondemolition measurement for quantum-enhanced atom interferometry
journal contribution
posted on 2023-06-09, 22:57 authored by Michail Kritsotakis, Jacob DunninghamJacob Dunningham, Simon A HaineWe theoretically investigate the use of quantum nondemolition measurement to enhance the sensitivity of atom interferometry with Bose-condensed atoms. In particular, we are concerned with enhancing existing high-precision atom interferometry apparatuses, and so restrict ourselves to dilute atomic samples and the use of free-propagating light or optical cavities in the weak-coupling regime. We find the optimum parameter regime that balances between spin squeezing and atomic loss and find that significant improvements in sensitivity are possible. Finally, we consider the use of squeezed light and show that this can provide further boosts to sensitivity.
