Probabilities (and more) from entanglement — •Wojciech Zurek — Theory, Los Alamos

I will discuss consequences of envariance (entanglement - assisted invariance; symmetry exhibited by entangled quantum states). I shall focus on implications of envariance for the understanding of the origins and nature of ignorance, and, hence, for the origin of probabilities in physics. While the derivation of the Born’s rule for probabilities (p_k = |ψ_k|²) is the principal result of this research, I shall explore the possibility that several other symptoms of the quantum - classical transition that are a consequence of decoherence can be justified directly by envariance – i.e., without invoking Born’s rule.
