The present disclosure provides a method and device for determining filters in a superconducting
quantum chip, and related equipment, relating to the technical field of
quantum computing, and particularly to the technical field of superconducting
quantum chips. The specific implementation scheme is as follows: determining the center frequencies of
two band-stop filters based on the
center frequency of a quantum bit of the superconducting quantum
chip; determining the lengths of the
two band-stop filters based on the center frequencies of the
two band-stop filters; and determining the
line segment length of a
target line segment of a readout line between the two band-stop filters as the distance between the two band-stop filters based on the
operating frequency range of the quantum bit; wherein the two band-stop filters are connected to the readout line, and the readout line between the two band-stop filters is coupled to a readout cavity so that the two band-stop filters are distributed on both sides of the readout cavity. In the present disclosure, based on the
center frequency of the quantum bit, the key parameters of the band-stop filter can be designed to improve the decoherence time of the quantum bit, and the entire
process design is simple and easy to implement.
