Abstract:
1. A coupling system comprising: a first superconducting qubit comprising a qubit loop formed by a closed superconducting current path and a compound Josephson junction that interrupts the qubit loop, wherein the compound Josephson junction is formed by a closed superconducting current path that is interrupted by at least two Josephson junctions; a second superconducting qubit comprising a qubit loop formed by a closed superconducting current path and a compound Josephson junction that interrupts the qubit loop, wherein the compound Josephson junction is formed by a closed superconducting current path that is interrupted by at least two Josephson junctions; and a first coupling device that is formed by a closed superconducting current path, wherein the first coupling device is communicably coupleable to the qubit loop of the first qubit and communicably coupleable to the compound Josephson junction of the second qubit.
