The occurrence of Bell non-locality, observations that cannot be explained in terms of local influences, is one of the most remarkable features of quantum theory. A new test of non-locality, tailored for quantum networks, has now been implemented in a network with two independent quantum sources.

违反量子网络中的双局部性

贝尔非局部性的出现（无法用局部影响来解释的观察结果）是量子理论最显着的特征之一。针对量子网络量身定制的一种新的非局域性测试，现已在具有两个独立量子源的网络中实施。
