We describe the linearly damped harmonic quantum oscillator in Heisenberg's interpretation by Onsager's thermodynamic equations.Ehrenfest's theorem is also discussed in this framework.We have also shown that the quantum mechanics of the dissipative processes exponentially decay to classical statistical theory.
