论文摘要
我们采用资源理论框架来根据位于网络上的操作约束来对不同类型的量子网络进行分类。一种类型的约束限制了各方在纯稳定器状态下执行局部克利福德门，我们表明量子网络非局部性在这种情况下不会出现。但是，如果放宽约束以允许混合稳定剂状态，则确实可以获得网络非局部性。我们还表明，双方纠缠足以生成所有形式的量子网络非局部性，允许后选择后，类似于双分部分纠缠的通用性，用于生成各种形式的多部分纠缠状态。
We adopt a resource-theoretic framework to classify different types of quantum network nonlocality in terms of operational constraints placed on the network. One type of constraint limits the parties to perform local Clifford gates on pure stabilizer states, and we show that quantum network nonlocality cannot emerge in this setting. Yet, if the constraint is relaxed to allow for mixed stabilizer states, then network nonlocality can indeed be obtained. We additionally show that bipartite entanglement is sufficient for generating all forms of quantum network nonlocality when allowing for post-selection, a property analogous to the universality of bipartite entanglement for generating all forms of multipartite entangled states.
