    "abstract": "Correspondence in quantum chaotic systems is lost in short time scales.\nIntroducing some noise we study the spectrum of the resulting coarse grained\npropagaor of density matrices. Some differen methods to compute the spectrum\nare reviewed. Moreover, the relationship between the eigenvalues of the\ncoarse-grained superoperator and the classical Ruelle-Pollicott resonances is\nremarked. As a concequence, classical decay rates in quantum time dependent\nquantities appear.",
