DESCRIPTION:Title: Quantum correlations in interacting primordial inhomoge
 neities Abstract: The statistical properties of the CMB anisotropies\, re
 flecting the curvature inhomogeneities in the early Universe\, are very we
 ll accounted for by assuming that they emerged from amplified vacuum fluct
 uations. Being the result of a genuine quantum process\, it is natural to 
 wonder which properties of these primordial inhomogeneities are quantum\, 
 and which\, if any\, persisted until their observations despite interacti
 ons that decohered\, i.e. classicalised\, them. I will review the latest p
 rogress on these questions\, emphasising the quantum information approache
