Self-consistent quasi-particle and hybrid functional calculations for Al/InAs/Al heterojunctions: band offset and spin-orbit coupling effects
H. Ness, F. Corsetti, D. Pashov +4
The electronic structure of surfaces and interfaces plays a key role in the properties of quantum devices. Here, we study the electronic structure of realistic Al/InAs/Al heterojun…
Few-mode to mesoscopic junctions in gatemon qubits
Alisa Danilenko, Deividas Sabonis, Georg W. Winkler +3
We investigate a semiconductor nanowire-based gatemon qubit with epitaxial Al on two facets of the nanowire, allowing gate control of wire density. Two segments have the Al removed…
Gate-Tunable Transmon Using Selective-Area-Grown Superconductor-Semiconductor Hybrid Structures on Silicon
A. Hertel, M. Eichinger, L. O. Andersen +12
We present a gate-voltage tunable transmon qubit (gatemon) based on planar InAs nanowires that are selectively grown on a high resistivity silicon substrate using III-V buffer laye…
Radio-frequency C-V measurements with sub-attofarad sensitivity
Filip K. Malinowski, Lin Han, Damaz de Jong +9
We demonstrate the use of radio-frequency (rf) resonators to measure the capacitance of nano-scale semiconducting devices in field-effect transistor configurations. The rf resonato…
Electrical Properties of Selective-Area-Grown Superconductor-Semiconductor Hybrid Structures on Silicon
A. Hertel, L. O. Andersen, D. M. T. van Zanten +9
We present a superconductor-semiconductor material system that is both scalable and monolithically integrated on a silicon substrate. It uses selective area growth of Al-InAs hybri…
Rapid microwave-only characterization and readout of quantum dots using multiplexed gigahertz-frequency resonators
Damaz de Jong, Christian Prosko, Daan M. A. Waardenburg +6
Superconducting resonators enable fast characterization and readout of mesoscopic quantum devices. Finding ways to perform measurements of interest on such devices using resonators…
