1206.5189 (Art Hobson)

Solution of the quantum measurement problem    [PDF]

Art Hobson
A close look at the post-measurement (pm) state of a system S and apparatus A resolves the measurement problem. Einstein causality prohibits local access to the pm state's nonlocal features, implying that S and A collapse into individual decohered states while the pm state evolves unitarily. S and A, connected only nonlocally, must be considered to be individual systems. The pm state is a superposition of correlations, not of states, so Schroedinger's cat is not in a superposition. Nonlocality experiments (Rarity and Tapster, Mandel) spectacularly confirm all this.
