Paper in Nature Photonics on long sought-after regime in quantum optics

A paper published in Nature Photonics, Dynamic resonance fluorescence in solid-state cavity quantum electrodynamics report the direct observation and systematic investigations of dynamic resonance fluorescence spectra beyond the Mollow-triplet in a solid-state cavity quantum electrodynamic system. This work facilitates the generation of a variety of exotic quantum states of light with dynamic driving of two-level systems.
