Abstract: The present disclosure provides a method and apparatus for coupling a superconducting qubit. The method includes: determining a target coupling strength between a target read cavity and a qubit, a first target frequency of the qubit, and a second target frequency of the target read cavity; initializing a read coupling port configuration layout based on a configuration of the qubit, a relative position of the qubit to the target read cavity; calculating a to-be-measured coupling strength between the qubit and the read coupling port, based on the read coupling port configuration layout, the first target frequency, and the second target frequency; and in response to detecting that the to-be-measured coupling strength and the target coupling strength satisfy a preset condition, generating, based on the second target frequency and the read coupling port configuration layout, a complete layout comprising the qubit and the target read cavity.

Abstract: Provided is a simulation method, electronic device, and storage medium relating to the field quantum computers and quantum simulation. The simulation method can include obtaining a first normal mode frequency of a first target device with adjustable frequency among at least two devices of a quantum chip layout through simulation; determining resonance-related information of the first target device and a second target device in a resonant state among the at least two devices; where the second target device is a device with adjustable or non-adjustable frequency among the at least two devices; and obtaining a target coupling strength between the first and second target devices based on the first normal mode frequency of the first target device and the resonance-related information.
