Abstract：The preparation of the quantum C-NOT gate is studied in this paper.The Caftan decomposition and the Lyapunov control methods are used to design the control laws for two single-qubit operations in realizing the C-NOT gate.The numerical simulation experiments show that for some proper control parameters in the designed control laws,each single qubit rotation has less deviation around the considered axis,and the total Fidelity of the system can achieve to 1,after 1.68 a.u..
