Abstract: A method is provided. The method includes determining a corresponding relationship between a pulse enveloping parameter and a single pulse duration, and determining a parameter to be optimized; and determining a maximum pulse number, an initialized current pulse number and a preset error tolerance. The method further includes executing an iterative operation including determining a quantum gate matrix to be implemented and a value of a loss function based on the current pulse number and the parameter to be optimized; adjusting a group of parameter values of the parameter to be optimized to minimize the value of the loss function; determining an error with a target quantum gate matrix after the value of the loss function is minimized; and in response to that the current pulse number is less than the maximum pulse number and the error is greater than the error tolerance, adding one to the current pulse number.
