Title:
SUPERCONDUCTING QUANTUM CIRCUIT
Document Type and Number:
Japanese Patent JP2023071448
Kind Code:
A
Abstract:
To provide a superconducting quantum circuit which enables the resonance operation point thereof to be easily adjusted.SOLUTION: A superconducting quantum circuit includes loop structure in which a first superconducting line, a first Josephson junction, a second superconducting line, and a second Josephson junction are circularly connected, and connects a plurality of SQUIDs (Superconducting Quantum Interference Devices) in parallel having a different in a junction area of the first Josephson junction and a junction area of the second Josephson junction. In the plurality of SQUIDs, any one of 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 and the junction area of the second Josephson junction is/are different each other between the plurality of SQUIDs.SELECTED DRAWING: Figure 2A
