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…
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…
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…
Twisted van der Waals Josephson junction based on high-Tc superconductor
Jongyun Lee, Wonjun Lee, Gi-Yeop Kim +8
Stacking two-dimensional van der Waals (vdW) materials rotated with respect to each other show versatility for the study of exotic quantum phenomena. Especially, anisotropic layere…
Steady Floquet-Andreev States Probed by Tunnelling Spectroscopy
Sein Park, Wonjun Lee, Seong Jang +7
Engineering quantum states through light-matter interaction has created a new paradigm in condensed matter physics. A representative example is the Floquet-Bloch state, which is ge…
Characterization of Shapiro steps in the presence of a 4π-periodic Josephson current
Jinho Park, Yong-Bin Choi, Gil-Ho Lee +1
The Majorana zero-energy modes (MZMs) residing at the boundary of topological superconductors have attracted a great deal of interest recently, as they provide a platform to explor…
Evidence of Higher Order Topology in Multilayer WTe from Josephson Coupling through Anisotropic Hinge States
Yong-Bin Choi, Yingming Xie, Chui-Zhen Chen +12
The noncentrosymmetric Td-WTe, previously known as a type-II Weyl semimetal, is expected to have higher order topological phases with topologically protected, helical one-dimen…
Short Ballistic Josephson Coupling in Planar Graphene Junctions with Inhomogeneous Carrier Doping
Jinho Park, Jae Hyeong Lee, Gil-Ho Lee +5
We report on short ballistic (SB) Josephson coupling in junctions embedded in a planar heterostructure of graphene. Ballistic Josephson coupling is confirmed by the Fabry-Perot-typ…
