论文摘要
许多三方相关性，包括一些通常被描述为真正三方非本地的相关性，可以通过仅显示双分裂非信号非局部行为的基础子系统网络来模拟。量子力学预测了未接收这种模拟的三方相关性，这表明自然界中存在非局部性的版本，超越了两部分非信号非局部性的现象。本文介绍了一个严格的框架，用于分析三方相关性，该框架可以通过仅两部分网络模拟。我们确认，所谓的相关性的预期性质，例如无信号，确实存在，并展示了如何使用该框架在这些相关性上得出贝尔 - 质量型的约束，这些相关性可能会被Tripartite量子量子系统违反。特别是，我们使用此框架来重新绘制一个以前在Chao and Reichardt（Arxiv：1706.02008）的论文中描述的这种约束的版本。
Many three-party correlations, including some that are commonly described as genuinely tripartite nonlocal, can be simulated by a network of underlying subsystems that display only bipartite nonsignaling nonlocal behavior. Quantum mechanics predicts three-party correlations that admit no such simulation, suggesting there are versions of nonlocality in nature transcending the phenomenon of bipartite nonsignaling nonlocality. This paper introduces a rigorous framework for analyzing tripartite correlations that can be simulated by bipartite-only networks. We confirm that expected properties of so-obtained correlations, such as no-signaling, indeed hold, and show how to use the framework to derive Bell-inequality-type constraints on these correlations that can be robustly violated by tripartite quantum systems. In particular, we use this framework to rederive a version of one such constraint previously described in a paper of Chao and Reichardt (arXiv:1706.02008).
