摘要：
The control of the state of a system to a given state has important applications in quantum engineering and control. In this paper, we study a control scheme that controls the localization of state in a two-level system via homodyne feedback, and analyse the condition for the steady state and stability of the localization. We also give the parameters of the feedback and the driving field for control of the system state to localization at any desired state on the Bloch sphere.
