论文摘要
在有关$ k $ locality（$ k \ geq2 $）网络的文献中，本地隐藏变量严格分布在特定的观察者中，而不是整个观察者中。关于真正的钟形区域，所有局部隐藏变量，作为允许在古典物理学中进行完美克隆的经典对象，都应克隆，然后在整个网络中分布。更多的相关因素参与了提出的线性和非线性钟形式不平等，其中其上限由预定的输出概率分布指定。至于量子版本，无克隆定理限制了量子相关性的广播。为了探索网络中变异粒子分布中的真正铃铛非局部性，保利操作员稳定了两Qubit的铃铛状态或多Qubit Greenberger- -Horne-Horne-Zeilinger-Zeilinger-Zeilinger-states（GHz States）在设计拟议的线性和非线性铃铛测试中起着至关重要的作用，并为当地的无线性铃铛测试并为Spatients Spate的观察者分配了不可或缺的测量。我们证明了对拟议的钟形不平等量量子网络的最大侵犯。最后，证明了纠缠交换如何取代贝尔测试中的关节测量值。
In the literature on $K$-locality ($K\geq2$) networks, the local hidden variables are strictly distributed in the specific observers rather than the whole ones. Regarding genuine Bell locality, all local hidden variables, as classical objects that allow for perfect cloning in classical physics, should be cloned and then spread throughout the networks. More correlators are involved in the proposed linear and non-linear Bell-type inequalities, where their upper bounds are specified by the pre-determined output probability distribution. As for the quantum version, the no-clone theorem limits the broadcast of quantum correlations. To explore genuine Bell nonlocality in variant particle distributions in the networks, the Pauli operators stabilizing the two-qubit Bell states or multi-qubit Greenberger--Horne--Zeilinger states (GHZ states) play an essential role in designing the proposed linear and non-linear Bell tests and assigning the local incompatible measurements for the spatially separated observers. We prove the maximal violations of the proposed Bell-type inequalities quantum networks. In the end, how entanglement swapping replaces the joint measurements in the Bell tests is demonstrated.
