Abstract
A quantum circuit device includes a qubit chip including a plurality of qubits and a plurality of flux tunable couplers. A plurality of fixed frequency qubits are arranged in in a lattice structure, wherein each pair of the plurality of fixed frequency qubits is coupled to one flux tunable coupler. A wiring layer is coupled to the qubit chip, and the wiring layer includes a loop constructed of a superconducting material that is inductively coupled to the flux tunable couplers. A flux bias line is constructed of a superconducting material that is different than the superconducting material of the loop, wherein the flux bias line is inductively coupled to both the loop and the flux tunable couplers.
