Based on the dynamics for non-Hermitian systems,a shortcut to adiabatic(STA)technique is analyzed in order to reliably manipulate quantum states more quickly.According to the numerical simulation results,the fast control of the quantum state can be achieved when the Hamiltonian of the system continuously evolves according to different gain and loss rates.This method not only has the characteristics of flexible and reliable design,but also has the advantages of low energy consumption.Therefore,this method has potential advantages in both theoretical and experimental implementation.Further extension and application of this method will provide effective help for faster control of quantum states.
