  In this Letter we consider stationary states of dissipative quantum systems.
We discuss stationary states of dissipative quantum systems, which coincide
with stationary states of Hamiltonian quantum systems. Dissipative quantum
systems with pure stationary states of linear harmonic oscillator are
suggested. We discuss bifurcations of stationary states for dissipative quantum
systems which are quantum analogs of classical dynamical bifurcations.
