作为Bell定理的一种推广,基于多纠缠源的量子网络及其非定域性被人们广泛关注。本文基于独立源假设研究多源星型量子网络,构建具有5个独立源和8个节点的非对称星型网络模型,并探究其量子非定域性。结果表明,对于分发到网络节点的一组指定的纠缠纯态,该量子网络模型下得到的5-local定域关联不等式将会被违背,当前量子网络模型具有明显的非定域特性。

A generalization of the Bell theorem leads to multi-source quantum network and its nonlocality, which have been widely studied. We construct a multi-source star-network with 5 sources and 8 nodes based on the assumption of source independence, and then we research its quantum nonlocality. As a result, a set of entangled sources can reveal quantum nonlocality of the present network configuration by violating the 5-local correlation inequalities.
