- Abstract: Compton scattering is one of the cornerstones of quantum physics, describing
the fundamental interaction of a charged particle with photons. The Compton
effect and its inverse are utilized in experiments driving free electrons by
high intensity lasers to create trains of attosecond X-ray pulses. So far, all
theory and experiments of the Compton effect and its generalizations have
relied on electromagnetic fields that can be described classically. Advances in
the generation of intense squeezed light could enable driving the Compton
effect with non-classical light. This outlook motivates exploring the role of
photon statistics in the Compton effect. We develop a framework to describe the
full non-perturbative interaction of a charged particle with a driving field
ascribed with an arbitrary quantum light state. We obtain analytical results
for the Compton emission spectrum when driven by thermal and squeezed vacuum
states, showing a noticeable broadening of the emission spectrum relative to a
classical (coherent state) drive, thus reaching higher emission frequencies for
the same average intensity. We envision utilizing the quantum properties of
light, including photon statistics, squeezing, and entanglement, as novel
degrees of freedom to control the wide range of radiation phenomena at the
foundations of quantum electrodynamics.

A single-pass quantum free-electron laser has a large interaction length that impedes the experimental realization.
Here we show that a quantum free-electron laser is closer to a coherent state in comparison to existing classical free-electron lasers.
The narrowing of the photon distribution implies reduced intensity fluctuations of the emitted radiation, which in turn lead to decreased noise in imaging experiments or to an enhanced sensitivity in interferometric applications.

Spontaneous emission is a fundamental out-of-equilibrium process in which an excited quantum emitter relaxes to the ground state due to quantum fluctuations.
One way to modify these photon-mediated interactions is to alter the dipole radiation patterns of the emitter, e.g., by placing photonic crystals near them.
Our study delves into the interaction between these directional emission patterns and the aforementioned variables, revealing the untapped potential to fine-tune collective quantum optical phenomena.

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.
