Non-Markovian dynamics of a qubit due to single-photon scattering in a waveguide

YLL Fang, F Ciccarello, HU Baranger - New Journal of Physics, 2018 - iopscience.iop.org
We investigate the open dynamics of a qubit due to scattering of a single photon in an
infinite or semi-infinite waveguide. Through an exact solution of the time-dependent multi …

Relationship between costs for quantum error mitigation and non-Markovian measures
