Graph representations are a powerful concept for solving complex problems\nacross natural science, as patterns of connectivity can give rise to a\nmultitude of emergent phenomena. Graph-based approaches have proven\nparticularly fruitful in quantum communication and quantum search algorithms in\nhighly branched quantum networks. Here we introduce a new paradigm for the\ndirect experimental realization of excitation dynamics associated with\nthree-dimensional networks by exploiting the hybrid action of spatial and\npolarization degrees of freedom of photon pairs in complex waveguide circuits\nwith tailored birefringence. This novel testbed for the experimental\nexploration of multi-particle quantum walks on complex, highly connected graphs\npaves the way towards exploiting the applicative potential of fermionic\ndynamics in integrated quantum photonics.\n
