Ground state phase diagram and "parity flipping'' microwave transitions in a gate-tunable Josephson Junction
M. R. Sahu, F. J. Matute-Cañadas, M. Benito +6
We probed a gate-tunable InAs nanowire Josephson weak link by coupling it to a microwave resonator. Tracking the resonator frequency shift when the weak link is close to pinch-off,…
Effects of the measurement power on states discrimination and dynamics in a circuit-QED experiment
L. Tosi, I. Lobato, M. F. Goffman +3
We explore the effects of driving a cavity at a large photon number in a circuit-QED experiment where the ``matter-like'' part corresponds to an unique Andreev level in a supercond…
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.…
Coherent manipulation of Andreev states in superconducting atomic contacts
C. Janvier, L. Tosi, L. Bretheau +9
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 electromag…
Superconducting Quantum Point Contacts
L. Bretheau, Ç. Girit, L. Tosi +5
We review our experiments on the electronic transport properties of atomic contacts between metallic electrodes, in particular superconducting ones. Despite ignorance of the exact…
Scaling Law in Carbon Nanotube Electromechanical Devices
R. Lefevre, M. F. Goffman, V. Derycke +4
We report a method for probing electromechanical properties of multiwalled carbon nanotubes(CNTs). This method is based on AFM measurements on a doubly clamped suspended CNT electr…
