Strong tunable coupling between a superconducting charge and phase qubit
A. Fay, E. Hoskinson, F. Lecocq +4
We have realized a tunable coupling over a large frequency range between an asymmetric Cooper pair transistor (charge qubit) and a dc SQUID (phase qubit). Our circuit enables the i…
Observation of transition from escape dynamics to underdamped phase diffusion in a Josephson junction
J. M. Kivioja, T. E. Nieminen, J. Claudon +3
We have investigated the dynamics of underdamped Josephson junctions. In addition to the usual crossover between macroscopic quantum tunnelling and thermally activated (TA) behavio…
Coherent low-energy charge transport in a diffusive S-N-S junction
P. Dubos, H. Courtois, O. Buisson +1
We have studied the current voltage characteristics of diffusive mesoscopic Nb-Cu-Nb Josephson junctions with highly-transparent Nb-Cu interfaces. We consider the low-voltage and h…
First experimental evidence of one-dimensional plasma modes in superconducting thin wires
B. Camarota, F. Parage, F. Balestro +2
We have studied niobium superconducting thin wires deposited onto a SrTiO substrate. By measuring the reflection coefficient of the wires, resonances are observed in the supe…
