Germanium quantum well Josephson field effect transistors and interferometers
Florian Vigneau, Raisei Mizokuchi, Dante Colao Zanuz +8
Hybrid superconductor-semiconductor structures attract increasing attention owing to a variety of potential applications in quantum computing devices. They can serve to the realiza…
Theory of Andreev Blockade in a Double Quantum Dot with a Superconducting Lead
David Pekker, Po Zhang, Sergey M. Frolov
A normal metal source reservoir can load two electrons onto a double quantum dot in the spin-triplet configuration. We show that if the drain lead of the dot is a spin-singlet supe…
Braidonium: a braiding quantum circuit based on the Josephson effect
John P. T. Stenger, Michael Hatridge, Sergey M. Frolov +1
We propose a topological qubit in which braiding and readout are mediated by the Majorana-Josephson effect. The braidonium device consists of three Majorana nanowires that com…
Mirage Andreev spectra generated by mesoscopic leads in nanowire quantum dots
Z. Su, A. Zarassi, J. -F. Hsu +15
We study transport mediated by Andreev bound states formed in InSb nanowire quantum dots. Two kinds of superconducting source and drain contacts are used: epitaxial Al/InSb devices…
Control and detection of Majorana bound states in quantum dot arrays
John P. T. Stenger, Benjamin D. Woods, Sergey M. Frolov +1
We study the low-energy physics of a one-dimensional array of superconducting quantum dots realized by proximity coupling a semiconductor nanowire to multiple superconducting islan…
