An rf Quantum Capacitance Parametric Amplifier
A. El Kass, C. T. Jin, J. D. Watson +4
We demonstrate a radio-frequency parametric amplifier that exploits the gate-tunable quantum capacitance of an ultra high mobility two dimensional electron gas (2DEG) in a GaAs het…
Local and Non-local Microwave Impedance of a Three-Terminal Hybrid Device
B. Harlech-Jones, S. J. Waddy, J. D. S. Witt +8
We report microwave impedance measurements of a superconductor-semiconductor hybrid nanowire device with three terminals (3T). Our technique makes use of transmission line resonato…
InAs-Al Hybrid Devices Passing the Topological Gap Protocol
Morteza Aghaee, Arun Akkala, Zulfi Alam +124
We present measurements and simulations of semiconductor-superconductor heterostructure devices that are consistent with the observation of topological superconductivity and Majora…
Probing quantum devices with radio-frequency reflectometry
Florian Vigneau, Federico Fedele, Anasua Chatterjee +5
Many important phenomena in quantum devices are dynamic, meaning that they cannot be studied using time-averaged measurements alone. Experiments that measure such transient effects…
Spin-Relaxation Mechanisms in InAs Quantum Well Heterostructures
J. D. S. Witt, S. J. Pauka, G. C. Gardner +6
The spin-orbit interaction and spin-relaxation mechanisms of a shallow InAs quantum well heterostructure are investigated by magnetoconductance measurements as a function of an app…
Building a Quantum Engineering Undergraduate Program
Abraham Asfaw, Alexandre Blais, Kenneth R. Brown +34
The rapidly growing quantum information science and engineering (QISE) industry will require both quantum-aware and quantum-proficient engineers at the bachelor's level. We provide…
