Quantum enhanced measurement of rotations with a spin-1 Bose-Einstein condensate in a ring trap
journal contribution
posted on 2023-06-09, 04:39 authored by Samuel P Nolan, Jacopo Sabbatini, Michael W J Bromley, Matthew J Davis, Simon A HaineWe present a model of a spin-squeezed rotation sensor utilizing the Sagnac effect in a spin-1 Bose-Einstein condensate in a ring trap. The two input states for the interferometer are seeded using Raman pulses with Laguerre-Gauss beams and are amplified by the bosonic enhancement of spin-exchange collisions, resulting in spin-squeezing and potential quantum enhancement of the interferometry. The ring geometry has an advantage over separated beam path atomic rotation sensors due to the uniform condensate density. We model the interferometer both analytically and numerically for realistic experimental parameters and find that significant quantum enhancement is possible, but this enhancement is partially degraded when working in a regime with strong atomic interactions.
