Patent ID: 7800395

Claim:
A coupling system to couple a first qubit and a second qubit, the coupling system comprising: a first loop of superconducting material; a second loop of superconducting material; a first Josephson junction interrupting the first and the second loops of superconducting material; a second Josephson junction interrupting the second loop of superconducting material; a first magnetic flux inductor that forms at least a portion of a first mutual inductance interface to inductively couple the first loop of superconducting material with the first qubit; a second magnetic flux inductor that forms at least a portion of a second mutual inductance interface to inductively couple the first and the second loops of superconducting material with the second qubit; a third magnetic flux inductor forming a third mutual inductance interface to inductively couple the first loop to a first coupling state control structure; and a fourth magnetic flux inductor forming a fourth mutual inductance interface to inductively couple the second loop to a second coupling state control structure.
