    "abstract": "A method for producing an upper bound for all multipartite purification\nprotocols is devised, based on knowing the optimal protocol for purifying\nbipartite states. When applied to a range of noise models, both local and\ncorrelated, the optimality of certain protocols can be demonstrated for a\nvariety of graph and valence bond states.",
