Abstract
Systems and methods are provided for coupling two qubits. A first persistent current qubit is fabricated with a first superconducting loop interrupted by a first Josephson junction isolated by a first inductor and a second inductor from a second Josephson junction. A second persistent current qubit is fabricated with a second superconducting loop interrupted by a third Josephson junction isolated by a third inductor and a fourth inductor from a fourth Josephson junction. Nodes defined by the Josephson junctions of the first qubit and their neighboring inductors are connected to corresponding nodes defined by the third Josephson junction and the third inductor via a first capacitor, with one pair of connections swapped such that the nodes are not connected to their respective corresponding nodes.
