量子系统辨识与参数估计

Quantum system identification and parameter estimation

量子信息的飞速发展对人们调控量子系统的能力提出了更高的要求,而对量子系统进行辨识与参数估计是进行量子控制的基本且重要的环节.本文综述量子系统辨识和参数估计这一方向,侧重于量子度量学、量子层析、量子滤波和量子噪声谱学4个分支,介绍其问题建模、分析工具、求解方法及不同的应用等.

The rapid development of quantum information poses demands for robust and high-precision control of quantum systems,while quantum system identification and parameter estimation are fundamentally important for quantum control.In this paper,we provide a survey on the direction of quantum system identification and parameter estimation,with emphasis on the four branches including quantum metrology,quantum tomography,quantum fltering,and quantum noise spectroscopy.The problem formulation,analysis tools,solutions,and various applications are introduced.
