OBSERVABLES, QUANTUM FLUCTUATIONS, AND "QUANTUM REALITY"

AUTHOR(S) INFORMATION: Shumovsky A.S.

ABSTRACT

We discuss difference between the classical and quantum methods of description of Nature in terms of fundamental observables related to the dynamical symmetry group of the Hilbert space and quantum fluctuations, specifying their measurement. We show that the total amount of quantum fluctuations of fundamental observables can be used to measure the “remoteness” of quantum states from “classical reality” provided by the choice of observables in terms of c-numbers. The proposed picture is more general than Bell's approach to definition of “classical reality”.
