First Measurement of Correlated Charge Noise in Superconducting Qubits at an Underground Facility
G. Bratrud, S. Lewis, K. Anyang +35
We measure space- and time-correlated charge jumps on a four-qubit device, operating 107 meters below the Earth's surface in a low-radiation, cryogenic facility designed for the ch…

Statistics of Strongly Coupled Defects in Superconducting Qubits
S. Weeden, D. C. Harrison, S. Patel +8
Decoherence in superconducting qubits is dominated by defects that reside at amorphous interfaces. Interaction with discrete defects results in dropouts that complicate qubit opera…

Design and Characterization of a Phonon-Mediated Cryogenic Particle Detector with an eV-Scale Threshold and 100 keV-Scale Dynamic Range
R. Ren, C. Bathurst, Y. Y. Chang +27
We present the design and characterization of a cryogenic phonon-sensitive 1-gram Si detector exploiting the Neganov-Trofimov-Luke effect to detect single-charge excitations. This…
