Multichannel interference giving rise to Fano-resonant lineshapes has long been utilized for extreme enhancement of signal to noise among widely varied sensing applications. Nevertheless, the engineering of such an effect has yet to provide similar gains for quantum optical applications. For the first time, however, we have harnessed the enhancement of a Fano resonance to interferometrically extract the quantum fluctuations of scattered light from a strongly-driven cavity quantum electrodynamical (cQED) system. Having exploited this interference for an unconventional self-homodyne measurement, we reveal the elusive incoherently-scattered light from a dynamic Mollow triplet in a solid-state environment. This application of interferometric scattering will enable devices that overcome the highly dissipative nature of solid-state systems and thus allow for the creation of high-throughput nonclassical light sources and all-optical single-photon transistors.
