Abstract
A formalism to connect entanglement witnesses and the distillation and activation properties of a state was introduced. The formalism was applied to two cases namely, that one copy of any bipartite state with nonpositive partial transpose (NPPT) was either distillable, or activatable. Secondly, three-partite NPPT states were shown to exist, with the property that two copies could neither be distilled, nor activated.
