Query: Suppression of 1/f noise in solid state quantum devices by surface spin
  desorption   Noise and decoherence due to spurious two-level systems (TLS) located at
material interfaces is a long-standing issue in solid state quantum
technologies. Efforts to mitigate the effects of TLS have been hampered by a
lack of surface analysis tools sensitive enough to identify their chemical and
physical nature. Here we measure the dielectric loss, frequency noise and
electron spin resonance (ESR) spectrum in superconducting resonators and
demonstrate that desorption of surface spins is accompanied by an almost
tenfold reduction in the frequency noise. We provide experimental evidence that
simultaneously reveals the chemical signatures of adsorbed magnetic moments and
demonstrates their coupling via the electric-field degree of freedom to the
resonator, causing dielectric (charge) noise in solid state quantum devices.
