基于数值迭代的两能级封闭量子系统最优控制
The optimal control of two-level closed quantum system based on numerical iteration
摘要
Abstract
The expected performance index is the foundation for all of control systems.The re-search on the control of quantum systems mainly focus on a unique obj ect such as the precision of final state,the minimum of time or energy,which lacks a comprehensive consideration on the ac-tual system.Based on the comprehensive analysis of the characteristic of the two-level closed quantum system,a comprehensive performance index leading to an optimal unitary evolution and energy is proposed in this paper.Then a group of differential equations of state and Lagrange multipliers which satisfies the optimality condition to the performance index is obtained based on the variation of performance index.Further,regarding the group of differential equations,a strategy for the solution of optimal control is designed based on numerical iteration with finite difference methods.Lastly,the influence of parameters to the control results is analyzed based on numerical simulation,and the effectiveness of the optimal control method and the iteration algo-rithm suggested in this paper is tested.关键词
