TL;DR: In the past 20 years, impressive progress has been made both experimentally and theoretically in superconducting quantum circuits, which provide a platform for manipulating microwave photons as mentioned in this paper, and many higher-order effects, unusual and less familiar in traditional cavity quantum electrodynamics with natural atoms, have been experimentally observed.

TL;DR: A review of ultrastrong coupling between light and matter can be found in this paper, where the authors discuss entangled ground states with virtual excitations, new avenues for nonlinear optics, and connections to several important physical models.

TL;DR: In this article, the authors review the theory of quantum systems with ultrastrong coupling, which includes entangled ground states with virtual excitations, new avenues for nonlinear optics, and connections to several important physical models.

TL;DR: This work shows that in a spinning Kerr resonator, PB happens when the resonator is driven in one direction but not the other, leading to a full split of the resonance frequencies of the countercirculating modes.
