Input-output formalism for few-photon transport in one-dimensional nanophotonic waveguides coupled to a qubit
Shanhui Fan, Şükrü Ekin Kocabaş, Jung‐Tsung Shen · Physical Review A · 2010
We extend the input-output formalism of quantum optics to analyze few-photon transport in waveguides with an embedded qubit. We provide explicit analytical derivations for one- and two-photon scattering matrix elements based on operator equations in the Heisenberg picture.
