Solving perfect matchings by frequency-grouped multi-photon events using a silicon chip

Abstract Computing the number of perfect matchings of a graph is a famous #P-complete problem. In this work, taking the advantages of the frequency dimension of photon, we propose and implement a photonic perfect matching solver, by combining two key techniques, frequency grouping and multi-photon c...
