In quantum physics, environmental noise represents the most prominent adversary that precludes the generation, control, and preservation of fundamental properties such as coherence, entanglement, and quantum correlations. More precisely, in such open quantum systems the phase properties of the associated quantum mechanical waves are randomly distorted by the environment, as a result their interference capability or ‘coherence’ tends to vanish. Indeed, the fragility of quantum coherence is one of the main impediments for the development of quantum-enhanced technologies. Clearly, identifying mechanisms to prevent or slow down decoherence effects in quantum systems is an issue of scientific and practical importance. Even though there exist some investigations examining the influence of decoherence and disorder on the dynamics of two-particle systems, the joint effects of decoherence, particle indistinguishability, and inter-particle interactions are poorly understood. The aim of this proposal is to investigate the behavior of multiple interacting particles traversing dynamically disordered quantum systems. In doing so, we have we will identify ways to impose tailored dynamic disorder into waveguide networks. The present proposal essentially interfaces theoretical and experimental investigations of the open quantum systems. Our studies will advance our understanding of the primary physical events occurring in quantum complex systems. In addition, our work will help to identify potential applications of decoherence to control photon encoded information and many-body quantum correlations. Importantly, our theoretical findings will always be tested experimentally within the context of integrated quantum photonics.
