Identification of quantum system parameters of the electron spin system controlled by magnetic field
磁场控制下的电子自旋量子系统参数辨识

The knowledge of the performance parameter of the quantum control system is crucial to the design of an accurate controller. Based on the quantum process tomography, we propose a method for identifying quantum control system parameters. The identified parameters are employed in the specific programs for designing the magnetic field control in an electron spin system. Computer simulations are carried out for the programs. The results show that the identified values of quantum control system parameters are comparatively consistent with the theoretic values with desired accuracy. Theoretical analysis and simulation results validate the effectiveness in applying the quantum process tomography to the identification of the quantum control system parameters.
