Probability and Nonlocality in Many Minds Interpretations of Quantum Mechanics

Hemmo, Meir and Pitowsky, Itamar (2001) Probability and Nonlocality in Many Minds Interpretations of Quantum Mechanics.

Abstract

We argue that a certain type of many minds (and many worlds) interpretations of quantum mechanics, e.g. Lockwood ([1996a]), Deutsch ([1985]) do not provide a coherent interpretation of the quantum mechanical probabilistic algorithm. By contrast, in Albert and Loewer's ([1988]) version of the many minds interpretation there is a coherent interpretation of the quantum mechanical probabilities. We consider Albert and Loewer's probability interpretation in the context of Bell-type and GHZ-type states and argue that it implies a certain (weak) form of nonlocality.
