We report a graph-based very-large-scale-integrated silicon-photonic quantum chip. Having the correspondence between quantum chip and graph theory, we demonstrate the generation of multiphoton multidimensional entanglement and determination of modulussquared Hafnian (Permanent) of graph’s adjacency matrices.
