Abstract:
In isolated quantum mechanical systems, solutions to the Schrödinger equation exist such that amplitude interference is maintained (in time) between states with widely different macroscopic properties. An engineering criteria for the required isolation is given in terms of a generalized Josephson law, valid for an arbitrary question in the sense of quantum measurement theory.
