Description
We present a proposal for implementing cavity quantum electrodynamics (cavity QED) with cold molecules to enable quantum-enhanced sensing for fundamental physics. By exploiting the rich internal structure of molecules, this approach has the potential to surpass the Standard Quantum Limit through engineered spin-squeezed states generated via strong light–matter coupling in a high-finesse optical cavity. We outline the experimental design under development, discuss key challenges such as complex multi-channel decay, and note that, on the theory side, we have identified detuning regimes where Raman-scattering-induced decoherence is sufficiently suppressed to allow non-destructive measurements. This work-in-progress aims to lay the foundation for performing precision measurements beyond the Standard Quantum Limit through the use of entangled states, opening new opportunities in the search for symmetry-violating moments, refined determinations of fundamental constants, and novel probes for dark matter.
