Within a passage comes this piece of physics:

"A system of separable state equations for double-photons is proposed, and is shown to lead to a violation of Bell’s inequality."

A system of separable state equations for double-photons is proposed --> Un système d’équations d'état séparables pour double photon ?!?
violation of Bell’s inequality --> violation de l'inégalité de Bell.
