Full Title
Also refereed to the postulate of wave packet reduction (WPR) which includes the effect that the measurement of one part of a system has on the knowledge about rest of the system.
Context
The first assumption of the Ghirardi, Rimini, and Weber theory is that the wave function (or state vector) represents the most accurate possible specification of the state of a physical system. This is a feature that the GRW theory shares with the standard Interpretations of quantum mechanics, and distinguishes it from hidden variable theories, like the de Broglie–Bohm theory, according to which the wave function does not give a complete description of a physical system. The GRW theory differs from standard quantum mechanics for the dynamical principles according to which the wave function evolves.[10][11] More philosophical issues related to the GRW theory and to collapse theories in general one have been discussed by Ghirardi and Bassi.[1]
