1. A quantum computing system for selectively shifting qubit resonance frequencies, the system comprising: a plurality of qubits including at least a first qubit and a second qubit, each of the first qubit and the second qubit having a respective resonance frequency; a plurality of coupling control resonators including at least a first coupling control resonator and a second coupling control resonator each having a respective resonance frequency band; and a coupling control signal line for feeding a coupling control signal to at least the first coupling control resonator and the second coupling control resonator, wherein the first coupling control resonator is configured to shift the resonance frequency of the first qubit when the coupling control signal includes a frequency component in the resonance frequency band of the first coupling control resonator, and wherein the second coupling control resonator is configured to shift the resonance frequency of the second qubit when the coupling control signal includes a frequency component in the resonance frequency band of the second coupling control resonator.
