Abstract: A method is provided. The method includes: obtaining a frequency of each phonon in an ion trap chip for implementing the quantum gate; determining a frequency of Raman light detuning corresponding to the control pulse and a frequency of a first phonon, where the first phonon is a phonon with a frequency in the ion trap chip closest to the frequency of Raman light detuning; initializing a first pulse sequence and determining a second pulse sequence based on the first pulse sequence, such that the first phonon is decoupled from an ion after the first pulse sequence and the second pulse sequence are successively applied to the ion trap chip; determining an objective function based on a distortion function corresponding to a quantum gate to be implemented; and adjusting an amplitude and a phase of the first pulse sequence and determining the second pulse sequence to minimize the objective function.
