摘要：

We study the relation between violation of Bell inequalities and distillability properties of quantum states. Recently, Dur [Phys. Rev. Lett. 87, 230402 (2002)] has shown that there are some multiparticle bound entangled states which are nonseparable and nondistallable, that violate a Bell inequality. We prove that for all the states violating this inequality there exists at least one splitting of the parties into two groups such that some pure-state entanglement can be distilled, obtaining a connection between Bell inequalities and bipartite distillable entanglement.
