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…
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…
Engineering Andreev Bound States for Thermal Sensing in Proximity Josephson Junctions
Woochan Jung, Ethan G Arnault, Bevin Huang +7
The thermal response of proximity Josephson junctions (JJs) is governed by the temperature ()-dependent occupation of Andreev bound states (ABS), making them promising candidate…
Unveiling Topological Hinge States in the Higher-Order Topological Insulator WTe Based on the Fractional Josephson Effect
Yong-Bin Choi, Jinho Park, Woochan Jung +3
Higher-order topological insulators (HOTIs) represent a novel class of topological materials, characterised by the emergence of topological boundary modes at dimensions two or more…
