The utility of transmission measurement has made it a target for quantum enhanced measurement strategies. Here we find if the length of an absorbing object is a controllable variable, then, via the Beer-Lambert law, classical strategies can be optimi

Coherent-state probes in appropriately designed all-pass ring resonators outperform any quantum probe single-pass absorption estimation strategy, including those using Fock or bright squeezed states.

By leveraging interference and resonance enhancement effects, we find all-pass ring resonators with coherent-state probes can estimate absorption more precisely than any quantum probe single-pass strategy, including those using squeezed or Fock state

We derive the fundamental quantum limits in estimating the absorption coefficient and refractive index of an analyte using all-pass ring resonators. We find coherent-states are optimal probes and can outperform any quantum probe single-pass strategy.

Quantum states of light have been shown to enhance precision in absorption estimation over classical strategies. By exploiting interference and resonant enhancement effects, we show that coherent-state probes in all-pass ring resonators can outperfor

Quantum fluctuations in the intensity of an optical probe is noise which limits measurement precision in absorption spectroscopy. Increased probe power can offer greater precision, however, this strategy is often constrained by sample saturation. Her
