On the phase uncertainty of Fock states and "nonlocal realism"
Based on the study of the effects of the suppression of cross-correlation of photons on a beam splitter and preparation of squeezed states, an experimental proof is proposed for the lack of determinate values of the phase and phase difference of photons in Fock states. It is shown that this conclusion unveils the intrinsic inconsistency of interpreting quantum mechanics on the basis of the nonlocal theory of hidden variables and proves the inadequacy of the latter.
