Relevancia causal de la medida en experimentos EPR: consideraciones ontológicas

Abstract

This paper addresses the ontological implications of a possible common cause model for the EPR correlations. The main characteristic feature of the model hast to do with the causal relevance, which is made explicit, of measurement operations for the postulated common causes, and hence as regards the final outcomes as well. These kind of dependences allow for the model to avoid the charge of Bell’s theorem, which is commonly taken to rule out explanations of the EPR correlations in terms of common causes. The model displays however a certain non-locality which suggests an ontological revision of the events involved. Two are the interpretations proposed for the postulated common causes. On the one hand, common causes may be viewed as non-localised events which operate causally in a local manner. Alternatively, the common cause events may be taken to be well defined localised events in space-time with nonlocal causal powers.
