Abstrakt

In his 1935 axiomatization of quantum mechanics, von Neumann postulated two very different types of change which quantum systems undergo: Schrödinger evolution and state vector reduction. Since that time, many attempts have been made to reconstruct or to reaxiomatize quantum theory so as to eliminate reduction or collapse and retain unitary evolution as the sole principle of change.
