Abstract
A superconducting quantum circuit includes a plurality of SQUIDs (Superconducting Quantum Interference Devices) connected in parallel, each of the plurality of SQUIDs including a first superconducting line, a first Josephson junction, a second superconducting line, and a second Josephson junction connected in a loop, wherein a junction area of the first Josephson junction and a junction area of the second Josephson junction are different from each other, the plurality of SQUIDs configured to be mutually different in either one or both of: a sum of the junction area of the first Josephson junction and the junction area of the second Josephson junction; and a ratio of the junction area of the first Josephson junction to the junction area of the second Josephson junction.
