    "abstract": "We show that entanglement-assisted transformations of bipartite entangled\nstates can be more efficient than catalysis [D. Jonathan and M. B. Plenio,\nPhys. Rev. Lett. 83, 3566 (1999)}, i.e., given two incomparable bipartite\nstates not only can the transformation be enabled by performing collective\noperations with an auxiliary entangled state, but the entanglement of the\nauxiliary state itself can be enhanced. We refer to this phenomenon as\nsupercatalysis. We provide results on the properties of supercatalysis and its\nrelationship with catalysis. In particular, we obtain a useful necessary and\nsufficient condition for catalysis, provide several sufficient conditions for\nsupercatalysis and study the extent to which entanglement of the auxiliary\nstate can be enhanced via supercatalysis.",
