Abstract: A method is provided that includes: determining a plurality of ions for generating a quantum gate; in response to determining that the plurality of ions are located in at least two ion trap sections, performing an ion shuttle operation through an ion shuttle channel, such that the plurality of ions are all located in a first ion trap section of the at least two ion trap sections; and generating a quantum gate based on the plurality of ions in the first ion trap section after the ion shuttle operation. The first quantum gate is to be generated based on an ion trap chip. The ion trap chip includes a plurality of ion trap sections, each of the plurality of ion trap sections includes no more than a first number of ions, and the plurality of ion trap sections are coupled through ion shuttle channels.

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.
