Non-Hermitian Quantum Nonlinear Optics with Single Photons
Samuel Napoli, Andrea Zappalá, Franco Nori +2
Quantum nonlinear optics seeks to harness strong photon-photon interactions for scalable quantum technologies, although dissipative losses still pose a major barrier to near-unity…

From Few to Many Emitters Cavity QED: Energy Levels and Emission Spectra From Weak to Deep-Strong Coupling
Andrea Zappalá, Alberto Mercurio, Daniele Lamberto +3
We present a systematic study of the properties of systems composed of two-level quantum emitters coupled to a single cavity mode, for light-matter interaction strengths rangin…

Circuit QED Spectra in the Ultrastrong Coupling Regime: How They Differ from Cavity QED
Samuel Napoli, Alberto Mercurio, Daniele Lamberto +3
Cavity quantum electrodynamics (QED) studies the interaction between resonator-confined radiation and natural atoms or other formally equivalent quantum excitations, under conditio…
