Space-saving coupler arm arrangement for superconducting qubits

A system, comprising:

• a superconducting qubit capacitively coupled to a group of coupler arms;
• wherein a first pair of coupler arms of the group of couplers are separated by a first defined distance selected to cause a first defined parasitic capacitance between a first coupler arm and a second coupler arm of the first pair of coupler arms that is within a first defined order of magnitude of a first defined capacitance between the superconducting qubit and at least one of the first pair of coupler arms, and wherein the first defined capacitance is selected to cause the first superconducting qubit to exhibit a defined quantum electrical behavior in response to presence of the first defined parasitic capacitance;
• and
• wherein a second pair of coupler arms of the group of couplers are separated by a second defined distance selected to cause a second defined parasitic capacitance between a first coupler arm and a second coupler arm of the second pair of coupler arms that is within a second defined order of magnitude of a second defined capacitance between the superconducting qubit and at least one of the second pair of coupler arms, and wherein the second defined capacitance is selected to cause the first superconducting qubit to exhibit the defined quantum electrical behavior in response to presence of the second defined parasitic capacitance.
