Probabilistic Interpretations

According to the current epistemic interpretation of quantum probabilities, the quantum correlations manifesting nonlocality can be derived from purely probabilistic and information-theoretic constraints. As such, they do not constitute a spacetime phenomenon and cannot lead to conflict between QM and any spatial-temporal constraints. This paper compares recent epistemic interpretations with earlier probabilistic interpretations, noting their merits as well as the difficulties they encounter. In particular, the implications of the recent PBR theorem are examined. While generally seen as undermining the epistemic interpretation, I argue that the PBR theorem actually suggests an epistemic position more radical than previously ones. This review of probabilistic interpretations enables reassessment of the epistemic theorist's attempt to disentangle nonlocality from spacetime considerations

The logical foundation of the probabilistic intrepretation of quantum-mechanical states is re-examined in view of Fukuda's new theory of measurement. We suggest that the probabilistic interpretation could be viewed as a natural consequence of the reduction of states upon meaurement, rather than an a priori ansatz contained in the “external observation” framework of quantum mechanics.
