Are Bell-tests only about local incompatibility?

论文摘要
观点认为，铃铛测试仅是关于量子可观察到的局部不相容性，而量子非局部性将是物理学中不必要的概念。在本说明中，我们强调的是，在地方一级并不兼容，这对于违反贝尔-Chsh不平等的行为很重要，而是在联合测量的非本地级别上不兼容。因此，非本地性仍然是正确解释某些联合量子测量结果的必要概念。
The view exists that Bell-tests would only be about local incompatibility of quantum observables and that quantum non-locality would be an unnecessary concept in physics. In this note, we emphasize that it is not incompatibility at the local level that is important for the violation of Bell-CHSH inequality, but incompatibility at the non-local level of the joint measurements. Hence, non-locality remains a necessary concept to properly interpret the outcomes of certain joint quantum measurements.
