We propose an experimental procedure for the optical implementation of quantum complex networks. The implementation of collections of systems arranged in a network structure with arbitrary complex topologies is still a non-trivial task in quantum experiments. We devise a mapping between complex networks and non-linear optical processes pumped by optical frequency combs followed by mode-selective detection. We show the deterministic implementation of reconfigurable networks. The platform has the potential to enable the experimental study of, e. g. , the dynamics of quantum states in complex networks and topological effects in quantum communication or information protocols over complex entanglement networks.
