    "abstract": "In the framework of Lindblad theory for open quantum systems, we calculate\nthe entropy of a damped quantum harmonic oscillator which is initially in a\nquasi-free state. The maximally predictable states are identified as those\nstates producing the minimum entropy increase after a long enough time. In\ngeneral, the states with a squeezing parameter depending on the environment\u0027s\ndiffusion coefficients and friction constant are singled out, but if the\nfriction constant is much smaller than the oscillator\u0027s frequency, coherent\nstates\n  (or thermalized coherent states) are obtained as the preferred classical\nstates.",
