Abstract: | In the framework of the Lindblad theory for open quantum systems, we determine the degree of quantum decoherence of a harmonic
oscillator interacting with a thermal bath. It is found that the system manifests a quantum decoherence which is more and
more significant in time. We also calculate the decoherence time and show that it has the same scale as the time after which
thermal fluctuations become comparable with quantum fluctuations.
