Abstract: The calculation of the non-Markovian dynamics of waveguide-QED systems with coherent time-delayed feedback within the Heisenberg picture gives access to the microscopic dynamics and allows the inclusion of dissipation channels. However, typically a hierarchy of multi-time correlations arises. We propose to unravel these multi-time correlations via a projection onto a complete set of states in the Hilbert space. In particular, we consider a two-level system inside a semi-infinite waveguide subjected to quantum light pulses. Our approach makes it possible to calculate the dynamics in a numerically exact and efficient manner for multiphoton pulses of arbitrary shape with memory requirements known a priori.
