本文研究了多体态的可量子化性与Bell不等式破坏之间的关系。我们证明了存在多体束缚纠缠态（即不可分纠缠态）。不可分割的状态），违反多方贝尔不等式。这意味着：（i）贝尔不等式的违反不是一个充分的条件，（ii）一些束缚纠缠态不能描述的本地隐变量模型。
We study the relation between distillability of multipartite states and violation of Bell's inequality. We prove that there exist multipartite bound entangled states (i.e,, nonseparable. nondistillable states) that violate a multipartite Bell inequality. This implies that (i) violation of Bell's inequality is not a sufficient condition for distillability and (ii) some bound entangled states cannot be described by a local hidden variable model.
