Autor: M F Goffman, C Urbina, H Pothier, J Nygård, C M Marcus, P Krogstrup
Publikováno v: New Journal of Physics, Vol 19, Iss 9, p 092002 (2017)
We present a quantitative characterization of an electrically tunable Josephson junction defined in an InAs nanowire proximitized by an epitaxially-grown superconducting Al shell. The gate-dependence of the number of conduction channels and of the se

Publikováno v: Physical Review X, Vol 9, Iss 1, p 011010 (2019)
We perform microwave spectroscopy of Andreev states in superconducting weak links tailored in an InAs-Al (core-full shell) epitaxially grown nanowire. The spectra present distinctive features with bundles of four lines crossing when the superconducti

Spectral properties of a quantum circuit are efficiently read out by monitoring the resonance frequency shift it induces in a microwave resonator coupled to it. When the two systems are strongly detuned, theory attributes the shift to an effective re

Coherent control of quantum states has been demonstrated in a variety of superconducting devices. In all these devices, the variables that are manipulated are collective electromagnetic degrees of freedom: charge, superconducting phase, or flux. Here

We describe a simple process for preparing sub-3 nm gaps by means of controllable breaking of gold wires lithographed on a SiO2/Si substrate at low temperature (4.2 K). We show that the mechanism involved is thermally assisted electromigration. We in
