Abstract
We study the relation between distillability of multipartite states and vio lation of Bell's inequality. We prove that there exist multipartite bound e ntangled states (i.e,, nonseparable. nondistillable states) that violate a multipartite Bell inequality. This implies that (i) violation of Bell's ine quality is not a sufficient condition for distillability and (ii) some boun d entangled states cannot be described by a local hidden variable model.
