论文摘要
非局部性是多部分量子相关性的最令人困惑的特征之一，已被确定为无独立的量子信息处理的有用资源。 Gallego等人最近提出了由量子纠缠的资源理论的动机。 [\ href {https://doi.org/10.1103/physrevlett.109.070401} {phys。莱特牧师。 109，070401（2012）}]和Bancal等。 [\ href {https://doi.org/10.1103/physreva.88.014102} {phys。 Rev. A 88，014102（2013）}]，它表征了多部分量子相关性中存在的非局部资源。虽然两分性的无信号相关性允许进行二分法分类 - 本地与非本地的相关性，在多部分场景中，作者表明，在提议的操作框架下存在几种类型的非局部性。在这项工作中，我们提出了基于相同的操作框架的多部分无信号相关性的更精细的表征。我们还阐明了在Gallego等人的作品中的一份声明，该声明可能会被误解，并在此处更精确地得出结论。
Nonlocality, one of the most puzzling features of multipartite quantum correlation, has been identified as a useful resource for device-independent quantum information processing. Motivated by the resource theory of quantum entanglement recently an operational framework have been proposed by Gallego et al. [\href{https://doi.org/10.1103/PhysRevLett.109.070401}{Phys. Rev. Lett. 109, 070401 (2012)}] and Bancal et al. [\href{https://doi.org/10.1103/PhysRevA.88.014102}{Phys. Rev. A 88, 014102 (2013)}] that characterizes the nonlocal resource present in multipartite quantum correlations. While the bipartite no-signaling correlations allows a dichotomous classification -- local vs. nonlocal, in multipartite scenario the authors have shown existence of several types of nonlocality that are inequivalent under the proposed operational framework. In this work we present a finer characterization of multipartite no-signaling correlations based on the same operational framework. We also clarify a statement in Gallego et al.'s work that could be misinterpreted and make the conclusions of that work more precise here.
