DESCRIPTION:In the framework of the theory of open systems based on comple
tely positive quantum dynamical semigroups\, we determine the degree of qu
antum decoherence of a harmonic oscillator interacting with a thermal bath
. We calculate the decoherence time and show that it has the same scale as
the time after which the statistical fluctuations become comparable with
the quantum fluctuations. The transition from quantum to classical behavio
r of the considered system is analyzed and it is shown that the classicali
ty takes place during a finite interval of time.\n\nhttps://indico.ipb.ac.
