1. A superconducting circuit structure, comprising:
at least three computational qubits;
a bus qubit connected to the at least three computational qubits, wherein couplings between two of the at least three computational qubits connected by the bus qubit are equivalent;
at least three coupler qubits, wherein a number of coupler qubits is same as a number of computational qubits, wherein each of the at least three coupler qubits is disposed between a respective computational qubit and the bus qubit, to connect the respective computational qubit to the bus qubit, and the each of the at least three coupler qubits is configured to regulate coupling strength between the respective computational qubit and the bus qubit; and
a first connector, a second connector, and a third connector,
wherein a first end of the bus qubit is connected to a first end of each of the at least three computational qubits through the first connector, a second end of the bus qubit is connected to a first end of each of the at least three coupler qubits through the second connector, and a second end of each of the at least three computational qubits is connected to a second end of a respective coupler qubit through the third connector.
