Signatures of interactions in the Andreev spectrum of nanowire Josephson junctions
F. J. Matute-Cañadas, C. Metzger, Sunghun Park +7
We performed microwave spectroscopy of an InAs nanowire between superconducting contacts implementing a finite-length, multi-channel Josephson weak link. Certain features in the sp…
Circuit-QED with phase-biased Josephson weak links
C. Metzger, Sunghun Park, L. Tosi +6
By coupling a superconducting weak link to a microwave resonator, recent experiments probed the spectrum and achieved the quantum manipulation of Andreev states in various systems.…
From adiabatic to dispersive readout of quantum circuits
Sunghun Park, C. Metzger, L. Tosi +4
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 system…
Spin-orbit splitting of Andreev states revealed by microwave spectroscopy
L. Tosi, C. Metzger, M. F. Goffman +6
We have performed microwave spectroscopy of Andreev states in superconducting weak links tailored in an InAs-Al (core-full shell) epitaxially-grown nanowire. The spectra present di…
Conduction Channels of an InAs-Al nanowire Josephson weak link
M. F. Goffman, C. Urbina, H. Pothier +3
We present a quantitative characterization of an electrically tunable Josephson junction defined in an InAs nanowire proximitized by an epitax-ially-grown superconducting Al shell.…
Theory of microwave spectroscopy of Andreev bound states with a Josephson junction
L. Bretheau, Ç. Girit, M. Houzet +3
We present a microscopic theory for the current through a tunnel Josephson junction coupled to a non-linear environment, which consists of an Andreev two-level system coupled to a…
