Abstract :
Purity evolution under a constant (Continuous-Wave) control field was investigated in this paper. It is shown that a resonant field has a decoupling effect, under which the purity fluctuation of the system states could be restricted in a certain range or even be eliminated. Quantum system numerical simulation experiments were given to demonstrate the properties of the purity and the effect of the resonant field.
