Energy relaxation via quantum thermalization: A superconducting qubit coupled to an interacting many-body two-level system
Xue-Yi Guo
Two-level systems (TLS) are widely recognized as a dominant source of energy relaxation in superconducting qubits, limiting coherence times and device performance. While TLS-induce…

Fabrication and Characterization of Impedance-transformed Josephson Parametric Amplifier
Zhengyang Mei, Xiaohui Song, Xueyi Guo +10
In this paper, we introduce a method of using a double-layer resist lift-off process to prepare the capacitor dielectric layer for fabricating impedance-engineered Josephson parame…
