Abstract
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.
摘要
我们研究了多体量子态的可提纯性与贝尔不等式违背之间的关系。我们证明存在违背多体贝尔不等式的多体束缚纠缠态（即不可分离、不可提纯的态）。这意味着：（i）违背贝尔不等式不是可提纯性的充分条件；（ii）一些束缚纠缠态不能用局域隐变量模型来描述。
