Theory and simulations of few-photon Fock state pulses strongly interacting with a single qubit in a waveguide: exact population dynamics and time-dependent spectra
Sofia Arranz Regidor, Andreas Knorr, Stephen Hughes
We present a detailed quantum theory and simulations of a few-photon Fock state pulse interacting with a two-level system (TLS) in a waveguide. For a rectangular pulse shape, we pr…
Dynamical spectra from one and two-photon Fock state pulses exciting a single chiral qubit in a waveguide
Sofia Arranz Regidor, Andreas Knorr, Stephen Hughes
We study the dynamical light emission from few-photon Fock states in waveguide-QED with a chiral two-level system. We first investigate the time dynamics of the system by calculati…
Modelling quantum light-matter interactions in waveguide-QED with retardation and a time-delayed feedback: matrix product states versus a space-discretized waveguide model
Sofia Arranz Regidor, Gavin Crowder, Howard Carmichael +1
We present two different methods for modelling non-Markovian quantum light-matter interactions in waveguide QED systems, using matrix product states (MPSs) and a space-discretized…
