Bell 测试只关乎局域不相容性吗?

Are Bell-tests only about local incompatibility?

Diederik Aerts, Massimiliano Sassoli de Bianchi

AI总结:

本文反驳 Bell 测试仅涉及局域不相容性的观点,指出 Bell-CHSH 不等式违反的关键在于联合测量的非局域不相容性,从而论证非局域性概念不可或缺。

摘要:

存在一种观点,认为 Bell 测试只关乎量子可观测量的局域不相容性,而量子非局域性在物理学中是一个不必要的概念。在本短文中,我们强调,对 Bell-CHSH 不等式的违反而言,重要的并非局域层面的不相容性,而是联合测量在非局域层面的不相容性。因此,非局域性仍是恰当解释某些联合量子测量结果所必需的概念。

英文摘要:

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.
