There is a recent article (Optics July 2015) claiming violation of Bell inequalities for classical fields:
"Shifting the quantum-classical boundary: theory and experiment for statistically classical optical fields"
https://www.osapublishing.org/optica/abstract.cfm?URI=optica-2-7-611
arxiv.org/pdf/1506.01305
It says that light's electric field in orthogonal directions behaves as superposition/entanglement.
Kind of dynamics of crystal lattice: we can see it as classical oscillations, or equivalently as superpositions of normal modes: phonons, which are described by quantum mechanics - can violate Bell inequalities.
What do you think about it?
