  Architectures based on waveguide quantum electrodynamics have emerged as
promising candidates for quantum networks. In this paper, we analyze the
propagation of single-photons in disordered many-atom waveguides. We pay
special attention to the influence of chirality (directionality of photon
transport) on the formation of localized photonic states, considering
separately the cases of the disorder in the atomic positions and in the atomic
transition frequencies.
