Discusses the feasibility of quantum measurements on macroscopic systems.

Abstract

The possibility to test quantum measurement theories is discussed in the more phenomenological framework of the quantum nondemolition theory. A simple test of the hypothesis of the state vector collapse is proposed by looking for deviations from the Boltzmann distribution of the energy associated to only one complex amplitude of a macroscopic harmonic oscillator.
