Revealing spin-flip two-level systems using ultra-thin film superconducting resonators
Zi-Qing Huang, Shu-Kun Ye, Yong-Qiang Xu +8
Material disorders are one of the major sources of noise and loss in solid-state quantum devices, whose behaviors are often modeled as two-level systems (TLSs) formed by charge tun…
