Suppression of low-frequency charge noise in superconducting resonators by surface spin desorption

The performance of solid-state quantum devices is often affected by low-frequency noise that appears to arise from the presence of two-level defects. Here the authors show that surface spins that cause magnetic noise are an origin of dielectric noise in superconducting resonators.
