Experimental principles for quantum-optical spectroscopy of materials

Abstract
We introduce an experimental methodology based on spectrally entangled biphoton states as a probe of many-body dynamics in materials. To that end, we present an experimental technique based on the Fourier transform spectroscopy to reliably estimate the spectral correlations between the entangled photons. In a proof-of-principle experiment, we transmit the biphoton state through a strongly coupled microcavity and reliably measure and analyze the variations in the spectral correlations between the photons.
