Abstract

A quantum sensing protocol is proposed for demonstrating the motion-induced
chirality of circularly polarised Rydberg atoms. To this end, a cloud of
Rydberg atoms is dressed by a bichromatic light field. This allows to exploit
the long-lived ground states for implementing a Ramsey interferometer in
conjunction with a spin echo pulse sequence for refocussing achiral
interactions. Optimal parameters for the dressing lasers are identified.
Combining a circularly polarised dipole transition in the Rydberg atom with
atomic centre-of-mass motion, the system becomes chiral. The resulting
discriminatory chiral energy shifts induced by a chiral mirror are estimated
using a macroscopic quantum electrodynamics approach.
