34. A word of caution is in order. This result is demonstrated for finite temperatures only, and might not be valid for T = 0. Nevertheless this result should remain true since the amount of decoherence necessary to kill the quantum correlations corresponds to add incoherently 1 photon to each mode, see Section III.C. That this is realized in inflationary cosmology remains to be seen.
