A coupling system may include an rf-SQUID having a loop of superconducting material interrupted by a compound Josephson junction; and a first magnetic flux inductor configured to selectively provide a mutual inductance coupling the first magnetic flux inductor to the compound Josephson junction, wherein the loop of superconducting material positioned with respect to a first and second qubits to provide respective mutual inductance coupling therebetween. The coupling system may further include a second magnetic flux inductor configured to selectively provide a second magnetic flux inductor mutual inductance coupling the second magnetic flux inductor to the compound Josephson junction. A superconducting processor may include the coupling system and two or more qubits. A method may include providing the first, the second and the third mutual inductances.
