    "abstract": "We introduce a formalism that connections entanglement witnesses and the\ndistillation and activation properties of a state. We apply this formalism to\ntwo cases: First, we rederive the results presented in quant-ph/0104095 by\nEggeling et al., namely that on copy of any bipartite state with non--positive\npartial transpose (NPPT) is either distillable, or activable. Second, we show\nthat there exist three--partite NPPT states, with the property that two copies\ncan neither be distilled, nor activated.",
