Input-Output Formalism For Few-Photon Transport in One-Dimensional Nanophotonic Waveguides Coupled to a Qubit

摘要

We extend the input-output formalism of quantum optics to analyze few-photontransport in waveguides with an embedded qubit. We provide explicit analyticalderivations for one and two-photon scattering matrix elements based on operatorequations in the Heisenberg picture.
