EPR中的因果关系、测量相关性和无共谋

Causation, Measurement Relevance and No-conspiracy in EPR

Iñaki San Pedro

摘要:

在本文中,我评估的充分性,没有阴谋的条件,在通常的推导过程中的贝尔不等式的EPR相关性。首先,我看EPR相关性从一个纯粹的现象学的角度来看,并声称这些共同原因的解释不能排除。我认为,一个适当的共同原因的解释要求,没有阴谋的条件被重新解释为仅仅是共同原因测量的独立性条件。在正确的情况下,违反度量独立性不需要任何形式的阴谋(也不需要时间因果关系)。相反,如果EPR背景下的测量操作被认为与实验结果以特定的方式存在因果关系,则它们明确的因果作用为相应相关性的共因解释提供了依据。

英文摘要:

In this paper I assess the adequacy of no-conspiracy conditions employed in the usual derivations of the Bell inequality in the context of EPR correlations. First, I look at the EPR correlations from a purely phenomenological point of view and claim that common cause explanations of these cannot be ruled out. I argue that an appropriate common cause explanation requires that no-conspiracy conditions are re-interpreted as mere common cause-measurement independence conditions. In the right circumstances then, violations of measurement independence need not entail any kind of conspiracy (nor backwards in time causation). To the contrary, if measurement operations in the EPR context are taken to be causally relevant in a specific way to the experiment outcomes, their explicit causal role provides the grounds for a common cause explanation of the corresponding correlations.
