  For harnessing the full potential of quantum phenomena, light-matter
interfaces and complexly connected quantum networks are required, relying on
the joint quantum operation of different physical platforms. In this work, we
analyze the quantum properties of multipartite quantum systems, consisting of
an arbitrarily large collection of optical cavities with two-level atoms. In
particular, we explore quantum walks in such systems and determine the
resulting entanglement. Realistic imperfections are included in the model as
optical losses and spontaneous decays of atoms. The topology of torus and the
non-orientable M\"obius strip serve as examples of complex networks we
consider, demonstrating the versatility of our approach and resulting in
interesting quantum dynamics and interference effects for quantum simulation
applications.
