Structural control of two-level defect density revealed by high-throughput correlative measurements of Josephson junctions
Oliver F. Wolff, Harshvardhan Mantry, Rahim Raja +8
Materials defects in Josephson junctions (JJs), often referred to as two-level systems (TLS), couple to superconducting qubits and are a critical bottleneck for scalable quantum pr…

High dynamic-range quantum sensing of magnons and their dynamics using a superconducting qubit
Sonia Rani, Xi Cao, Alejandro E. Baptista +2
Magnons can endow quantum devices with new functionalities. Assessing their potential requires precise characterization of magnon properties. Here, we use a superconducting qubit t…
