Implications of exceptional points for few-photon transport in waveguide quantum electrodynamics
Shanshan Xu, Shanhui Fan
We identify a general connection between the physics of exceptional points in non-Hermitian systems and the few-photon bound states in waveguide quantum electrodynamics (QED) syste…
Few-photon scattering and emission from open quantum systems
Rahul Trivedi, Kevin Fischer, Shanshan Xu +2
We show how to use the input-output formalism compute the propagator for an open quantum system, i.e. quantum networks with a low dimensional quantum system coupled to one or more…
Generate tensor network state by sequential single-photon scattering in waveguide QED systems
Shanshan Xu, Shanhui Fan
We propose a scheme to generate photonic tensor network states by sequential scattering of photons in waveguide QED systems. We show that sequential scatterings can convert a serie…
Input-Output Formalism for Few-Photon Transport: A Systematic Treatment Beyond Two Photons
Shanshan Xu, Shanhui Fan
We provide a systematic treatment of -photon transport in a waveguide coupled to a local system, using the input-output formalism. The main result of the paper is a general conn…
