Computation, Quantum Theory, and You
... Theorem: Under any dynamical theory satisfying the symmetry and indifference axioms, the first Fourier transform makes the hidden variable “forget” whether it was at |i or |j. So after the second Fourier transform, it goes to |i half the time and |j half the time; thus with ½ probability we see ...

This leads to creation of localized wave packets that travel in near-circular orbits and mimic the dynami ...
