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.For a systems consisting of two ind
 ependent harmonic oscillators interacting with a thermal bath we describe 
 the time evolution of the continuous-variable entanglement in terms of the
  covariance matrix of quantum states of the considered system for Gaussian
  input states.\n\nhttps://events.saifa.rs/event/233/
