Claim 10:
11. An apparatus, comprising:
a coupling structure coupled to a first qubit and a second qubit, the coupling structure having a plurality of coupling pathways configured to selectively produce multiple resonance modes, wherein at least one of the multiple resonance modes induces coupling of the first qubit to the second qubit to enable a resonator induced phase gate operation, wherein a group of other resonance modes of the multiple resonance modes inhibit coupling of the first qubit to the second qubit when the resonator induced phase gate operation is not enabled, and wherein a coupling pathway from the plurality of coupling pathways comprise a quarter wavelength superconducting waveguide capacitively coupled to the first qubit and the second qubit, wherein the quarter wavelength superconducting waveguide has multiple impedances.
