Realism and Time Symmetry in Quantum Mechanics

Quantum Physics 2009-10-28 v2

Abstract

We describe a gedanken experiment with an interferometer in the case of pre- and postselection in two different time symmetric ways: We apply the ABL formalism and the de Broglie--Bohm model. Interpreting these descriptions ontologically, we get two very different concepts of reality. Finally, we discuss some problems implied by these concepts.
