The progress of quantum computation technology is severely prevented by various imperfections.First,the effects of noise errors on the quantum computation of the quantum baker's map are compared with those of the static imperfections,and then,the dynamical decoupling methods are employed to tackle the static imperfections.As the noise errors are less destructive to the quantum simulation algorithm,the randomized dynamical control is used to suppress the disturbance of the static imperfections by equivalently transforming them into noise errors,thus enhancing the stability of the quantum simulation algorithm.Finally,simulation results of the fidelity decay confirm the validity of this method.
