A. S. Sheremet, Mihail I. Petrov, Ivan V. Iorsh, A. V. Poshakinskiy, Alexander N. Poddubny · Reviews of Modern Physics · 2023
Quantum emitters coupled to waveguides experience long-range interactions mediated by photons. This leads to superradiant and subradiant states, photon bound states, and various mechanisms for the preparation of entangled states of the emitters. This article reviews experiments on a wide range of systems and their description by theoretical methods and insights from different fields of physics.
