摘要
本文研究了量子C–NOT门的制备.Cartan分解和Lyapunov控制方法用于设计实现C–NOT门的两个量子位操作的控制手段.数值仿真实验表明,针对所设计的控制律,若给定合适的控制参数,每个单量子比特旋转在所考虑的轴周围具有较小的偏差,并且在1.68 a.u.
The preparation of the quantum C–NOT gate is studied in this paper.The Cartan 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..
