A superconducting circuit structure, a superconducting quantum chip, and a superconducting quantum computer are provided, which are related to a field of quantum computing. The specific implementation includes: a superconducting circuit structure, including: at least three computational qubits; a bus qubit connected to the respective computational qubits, wherein couplings between two of the computational qubits connected by the bus qubit are equivalent; and coupler qubits disposed between the respective computational qubits and the bus qubit, to connect the respective computational qubits to the bus qubits, wherein the coupler qubit is configured to regulate coupling strength between the computational qubit and the bus qubit. Couplings between any two computational qubits may be realized, so that an operation of a quantum gate between any two computational qubits is achieved, while crosstalk between computational qubits may be effectively suppressed.
