ABSTRACT
Quantum mechanics is a statistical theory (see, e.g., Margenau
[239, 240], Ballentine [25, 26], Klyshko [216], Holevo [115, 116],
Khrennikov [192]). It cannot tell us anything about an individual
quantum system, e.g., an electron or a photon. It predicts only
probabilities for results of measurements for large ensembles of
quantum systems. Classical statistical mechanics (CSM) does the same.Why are QM and CSM based on different probabilistic models?
