However, such an ad hoc model would not explain why such a preparation would correspond to this particular state, and it would not be generalizable to other evident anticorrelations from the very same state. The above quantum example also would exhibit anticorrelations if each photon were measured in the same diagonally polarized basis, while the ad hoc classical model would not.
 this "trivial" model is "ruled out from the beggining"
 why do they even mention it?
 Because the "anticorrelations" happen in EVERY angle, as log as, both detectors have the SAME angle
 That is so because the singlet state has rotational symmetry

We believe that this step has already beentaken, but not fully acknowledged, by a substantial part of the quantumopticscommunity. For example, three review articles (2−4) on light squeezing makeextensive use of phasespace diagrams, and one of them(3) states explicitly thatthe photon description of the light field is not helpful in the understanding ofthe phenomenon

The quantum harmonic oscillator is the quantum analog of the classical harmonic oscillator and is one of the most important model systems in quantum mechanics. This is due in partially to the fact that an arbitrary potential curve V(x)V(x)V(x) can usually be approximated as a harmonic potential at the vicinity of a stable equilibrium point. Furthermore, it is one of the few quantummechanical systems for which an exact, analytical solution exists. Solving other potentials typically require either approximations or numerical approaches to identify the corresponding eigenstates and eigenvalues (i.e., wavefunctions and energies).
