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…
Observing unconventional superconductivity via kinetic inductance in Weyl semimetal MoTe
Mary Kreidel, Julian Ingham, Xuanjing Chu +10
Identifying the pairing symmetry of unconventional superconductors plays an essential role in the ongoing quest to understand correlated electronic matter. A long-standing approach…
Roadmap: 2D Materials for Quantum Technologies
Qimin Yan, Tongcang Li, Xingyu Gao +29
Two-dimensional (2D) materials have emerged as a versatile and powerful platform for quantum technologies, offering atomic-scale control, strong quantum confinement, and seamless i…
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…
Crystalline superconductor-semiconductor Josephson junctions for compact superconducting qubits
Jesse Balgley, Jinho Park, Xuanjing Chu +11
The narrow bandgap of semiconductors allows for thick, uniform Josephson junction barriers, potentially enabling reproducible, stable, and compact superconducting qubits. We study…
Measuring kinetic inductance and superfluid stiffness of two-dimensional superconductors using high-quality transmission-line resonators
Mary Kreidel, Xuanjing Chu, Jesse Balgley +8
The discovery of van der Waals superconductors in recent years has generated a lot of excitement for their potentially novel pairing mechanisms. However, their typical atomic-scale…
