  • In the context of bipartite bosonic systems, two notions of classicality of correlations can be dened: P -classicality, based on the properties of the Glauber-Sudarshan P -function; and Cclassicality, based on the entropic quantum discord. It has been shown that these two notions are maximally inequivalent in a static (metric) sense | as they coincide only on a set of states of zero measure. We extend and reinforce quantitatively this inequivalence by addressing the dynamical relation between… CONTINUE READING
