- Abstract summary: We report a protocol that takes advantage of the strong and collective atom-light interactions in cavity QED systems for precise electric field sensing in the optical domain.
We show that it can provide between $10$-$20$dB of metro gain over the standard quantum limit in current cavity QED experiments operating with long-lived alkaline-earth atoms.

- Abstract: Macroscopic arrays of cold atoms trapped in optical cavities can reach the
strong atom-light collective coupling regime thanks to the simultaneous
interactions of the cavity mode with the atomic ensemble. In a recent work we
reported a protocol that takes advantage of the strong and collective
atom-light interactions in cavity QED systems for precise electric field
sensing in the optical domain. We showed that it can provide between
$10$-$20$~dB of metrological gain over the standard quantum limit in current
cavity QED experiments operating with long-lived alkaline-earth atoms. Here, we
give a more in depth discussion of the protocol using both exact analytical
calculations and numerical simulations, and describe the precise conditions
under which the predicted enhancement holds after thoroughly accounting for
both photon loss and spontaneous emission, natural decoherence mechanisms in
current experiments. The analysis presented here not only serves to benchmark
the protocol and its utility in cavity QED arrays but also sets the conditions
required for its applicability in other experimental platforms such as arrays
of trapped ions.
