Field-Dependent Qubit Flux Noise Simulated from Materials-Specific Disordered Exchange Interactions Between Paramagnetic Adsorbates
Keith G. Ray, Yaniv Rosen, Jonathan L Dubois +1
Superconducting quantum devices, from qubits and magnetometers to dark matter detectors, are influenced by magnetic flux noise originating from paramagnetic surface defects and imp…

A scanning probe microscopy approach for identifying defects in aluminum oxide
Leah Tom, Zachary J. Krebs, Joel B. Varley +8
The coherence of quantum dot qubits fabricated in semiconductors is often limited by charge noise from defects in gate dielectrics, which are material- and process-dependent. Chara…
