  The presence of disorder and inhomogeneities in quantum networks has often
been unexpectedly beneficial for both quantum and classical resources. Here, we
experimentally realize a controllable inhomogenous Quantum Walk dynamics, which
can be exploited to investigate the effect of coherent disorder on the quantum
correlations between two indistinguishable photons. Through the imposition of
suitable disorder configurations, we observe two photon states which exhibit an
enhancement in the quantum correlations between two modes of the network,
compared to the case of an ordered Quantum Walk. Different configurations of
disorder can steer the system towards different realizations of such an
enhancement, thus allowing spatial and temporal manipulation of quantum
correlations.
