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…
Simulating noise on a quantum processor: interactions between a qubit and resonant two-level system bath
Yujin Cho, Dipti Jasrasaria, Keith G. Ray +4
Material defects fundamentally limit the coherence times of superconducting qubits, and manufacturing completely defect-free devices is not yet possible. Therefore, understanding t…
Origin of Mechanical and Dielectric Losses from Two-Level Systems in Amorphous Silicon
M. Molina-Ruiz, Y. J. Rosen, H. C. Jacks +5
Amorphous silicon contains tunneling two-level systems, which are the dominant energy loss mechanisms for amorphous solids at low temperatures. These two-level systems affect both…
Anomalous Charge Noise in Superconducting Qubits
B. G. Christensen, C. D. Wilen, A. Opremcak +9
We have used Ramsey tomography to characterize charge noise in a weakly charge-sensitive superconducting qubit. We find a charge noise that scales with frequency as over 5…
