Coherent and compact van der Waals transmon qubits
Jesse Balgley, Jinho Park, Xuanjing Chu +9
State-of-the-art superconducting qubits rely on a limited set of thin-film materials. Expanding their materials palette can improve performance, extend operating regimes, and intro…

Measuring Reactive-Load Impedance with Transmission-Line Resonators Beyond the Perturbative Limit
Xuanjing Chu, Jinho Park, Jesse Balgley +8
We develop an analytic framework to extract circuit parameters and loss tangent from superconducting transmission-line resonators terminated by reactive loads, extending analysis b…
