Original Abstract Submitted

Systems and techniques that facilitate space-saving coupler arm arrangement for superconducting qubits are provided. In various embodiments, a device can comprise a superconducting qubit. In various aspects, the superconducting qubit can be capacitively coupled to two or more coupler arms. In various instances, a parasitic capacitance between the two or more coupler arms can be within an order of magnitude of a capacitance between the superconducting qubit and at least one of the two or more coupler arms. In various cases, the parasitic capacitance can arise due to a physical proximity between the two or more coupler arms.
