摘要：
It is shown that if quantum measurement results in a phase transition in a detector medium, then due to orthogonality of Fock spaces of different vacuums the final state cannot be distinguished from the mixture. Examples for transitions in ferromagnetic and vapor-liquid systems are considered. A new formalism is proposed in which EPR-Bohm nonlocal correlations are described as spontaneous symmetry breaking of the pair system state.
