Claim 0:
1. 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, wherein a coupling pathway from the plurality of coupling pathways is a resonator, wherein the first qubit is coupled to a first end of the resonator, and wherein the second qubit is coupled to a defined point along a length of the resonator selected to bring a qubit-qubit coupling frequency of the first qubit and the second qubit to a defined frequency difference from a resonance frequency of the resonator.
