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.
