Quantum decoherence and classical correlations of the harmonic oscillator in the Lindblad theory
arXiv:0705.2202 · doi:10.1016/j.physa.2006.04.065
Abstract
In the framework of the Lindblad theory for open quantum systems we determine the degree of quantum decoherence and classical correlations of a harmonic oscillator interacting with a thermal bath. The transition from quantum to classical behaviour of the considered system is analyzed and it is shown that the classicality takes place during a finite interval of time. We calculate also the decoherence time and show that it has the same scale as the time after which statistical fluctuations become comparable with quantum fluctuations.
