The modal interpretation of quantum mechanics and its generalization to density operators

Invited Papers Dedicated to Jean-Pierre Vigier

Abstract

We generalize the modal interpretation of quantum mechanics so that it may be applied to composite systems represented by arbitrary density operators. We discuss the interpretation these density operators receive and relate this to the discussion about the interpretation of proper and improper mixtures in the standard interpretation.
