摘要
测量独立性假设对于在局部现实条件下推导贝尔不等式至关重要。对这些不等式的违反表明,必须在一定程度上放宽测量独立性假设,以获得局部现实模型。霍尔(Phys Rev Lett 105:250404, 2010)和弗里德曼(Phys Rev A 99:012121, 2019)已经研究了需要在多大程度上放宽这一假设才能实现对某些双向贝尔不等式的违反。在本文中,我们研究了模拟违反各种已知三方贝尔不等式所需的最小松弛度。我们还提供了实现这些违反的局部确定性模型。
The assumption of measurement independence is essential for the derivation of Bell’s inequalities under local, realistic conditions. Violations of these inequalities indicate that the assumption of measurement independence must be relaxed to some extent in order to obtain locally realistic models. The extent to which this assumption needs to be relaxed to achieve violations of certain bipartite Bell inequalities has been studied in Hall (Phys Rev Lett 105:250404, 2010) and Friedman (Phys Rev A 99:012121, 2019). In this paper, we investigate the minimal degree of relaxation required to simulate violations of various known tripartite Bell inequalities. We also provide local deterministic models that achieve these violations.
