- Abstract: Cavity quantum electrodynamics (CQED) investigates the interaction between
light confined in a resonator and particles, such as atoms. In recent years,
CQED experiments have reached the optical domain resulting in many interesting
applications in the realm of quantum information processing. For many of these
application it is necessary to overcome limitations imposed by photon loss. In
this context whispering-gallery mode (WGM) resonators have obtained significant
interest. Besides their small mode volume and their ultra high quality, they
also exhibit favorable polarization properties that give rise to chiral
light--matter interaction. In this chapter, we will discuss the origin and the
consequences of these chiral features and we review recent achievements in this
area.

Recent theories have laid the groundwork for understanding how quantum-optical properties affect high-field photonics.
We demonstrate a new experimental approach that transduces some properties of a quantum-optical state through a strong-field nonlinearity.
Our results suggest that perturbing strong-field dynamics with quantum-optical states is a viable way to coherently control the generation of these states at short wavelengths.

free-electron-photons interactions [0.0]
We propose a scheme to generate optical cat states based on the quantum interference of multi-path free-electron-photons interactions.
We show that the Wigner negativity oscillates with the coupling strength, and the optical cat states are successfully generated with high fidelity.

spectroscopy [0.0]
The radiative quantum cascade, i.e. the consecutive emission of photons from a ladder of energy levels, is of fundamental importance in quantum optics.
Here, we use exciton polaritons to explore the cascaded emission of photons in the regime where individual transitions of the ladder are not resolved.
Remarkably, the measured photon-photon correlations exhibit a strong dependence on the polariton energy, and therefore on the underlying polaritonic interaction strength.

We find instead that the shockwave's duration is fundamentally bound from below by the particle's coherent momentum uncertainty.
