摘要：
The traditional quantum control theory focuses on linear quantum systems. Here we show the effect of nonlinearity on the quantum control of a two-level system, we find that the nonlinearity can change the controllability of the quantum system. Furthermore, we demonstrate that the Lyapunov control can be used to overcome this uncontrollability induced by the nonlinear effect.
