Strong coupling between a single-photon and a two-photon Fock state
Shuai-Peng Wang, Alberto Mercurio, Alessandro Ridolfo +9
The realization of strong nonlinear coupling between single photons has been a long-standing goal in quantum optics and quantum information science, promising wide impact applicati…
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…
Renormalization and Low-Energy Effective Models in Cavity and Circuit QED
Daniele Lamberto, Alberto Mercurio, Omar Di Stefano +2
The quantum Rabi model (QRM) is a cornerstone in the study of light-matter interactions within cavity and circuit quantum electrodynamics (QED). It effectively captures the dynamic…
Bilateral photon emission from a vibrating mirror and multiphoton entanglement generation
Alberto Mercurio, Enrico Russo, Fabio Mauceri +4
Entanglement plays a crucial role in the development of quantum-enabled devices. One significant objective is the deterministic creation and distribution of entangled states, achie…
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…
