Problem of realism in modern quantum mechanics. Materials of discussion

Abstract

This publication represents the materials of the discussion that took place in a form of a “round table” during the conference “Quantum Mechanics and Philosophical Discourse” (April 14–15, 2016, RAS Institute of Philosophy, Moscow, Russia). This discussion gives information, how the outcome of quantum experiments can chance the notion of reality. Experimental checks of Bell's theorem, Legett inequality, Leggett–Garg inequality and experimental delayed choice confirm, that for quantum objects it is necessary to revise classical realism very seriously. Different approaches to interpretation of observed phenomena also discussed. Within a framework of approach of modal metaphysics is shown how to resolve traditional paradoxes of quantum theory in particular it is shown for the first time what the “secret of quantum theory”, formulated by Richard Feynman, is related to.
