Abstract: A superconducting quantum processor unit for quantum computing is provided. The processor unit is formed from the union of a qubit chip and a wiring chip with superconducting bonding bumps and spacers. The bumps may be densely distributed around active elements between the two chips and effectively form a Faraday-Cage around the qubits, control signal waveguides etc. The qubit chip has strategically spaced qubits and an inductively coupled probe line and the wiring chip has a bus coupling resonator with a number of voltage nodes and anti-nodes, a resonator pump and at least one SQUID. Magnetic flux applied through the SQUIDs changes their impedances and modifies the microwave boundary conditions of the bus. This allows in-situ shifting of electric field distributions of the resonance modes of the bus along the length of the bus. This tunes the coupling rates of the bus to all qubits simultaneously.
