基于状态距离的量子控制策略
Quantum Control Strategy Based on State Distance
摘要
Abstract
Based on Bures distance, a Lyapunov function that represents the distance between a desired state and the actual state of a quantum system is selected. Considering the cases that an initial state is and is not orthogonal to the desired state respectively,we propose a class of control strategies with state feedback that ensures the stability of the closed-loop control system. Especially,the asymptotic stability of the control system is analyzed, deduced and proved in detail. Finally, a simulation experiment on a spin-1/2 particle system is done and the relation between the system state evolution time and control value is analyzed with different parameters . Research results have general theoretical meaning for control of quantum systems.关键词
