Quasiparticle poisoning of superconducting qubits with active gamma irradiation
C. P. Larson, E. Yelton, K. Dodge +5
When a high-energy particle, such as a -ray or muon, impacts the substrate of a superconducting qubit chip, large numbers of electron-hole pairs and phonons are created. The ens…

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…

Cryogenic User Facilities for R&D on Noble Liquid Detectors and Low Temperature Devices
Y. Li, C. Zhang, M. Diwan +13
Cryogenic test facilities are critical infrastructure for physics experiments in a variety of fields, perhaps most notably for particle detection with noble liquid detectors, low-t…
