Asymmetric noise probed with a Josephson junction
Q. Le Masne, H. Pothier, Norman O. Birge +2
Fluctuations of the current through a tunnel junction are measured using a Josephson junction. The current noise adds to the bias current of the Josephson junction and affects its…
Phase controlled superconducting proximity effect probed by tunneling spectroscopy
H. Le Sueur, P. Joyez, H. Pothier +2
Using a dual-mode STM-AFM microscope operating below 50mK we measured the Local Density of States (LDoS) along small normal wires connected at both ends to superconductors with dif…
Tunable resonators for quantum circuits
A. Palacios-Laloy, F. Nguyen, F. Mallet +3
We have designed, fabricated and measured high-Q coplanar waveguide microwave resonators whose resonance frequency is made tunable with magnetic field by inserting a DC-SQUID…
NMR-like control of a quantum bit superconducting circuit
E. Collin, G. Ithier, A. Aassime +3
Different nanofabricated superconducting circuits based on Josephson junctions have already achieved a degree of quantum coherence sufficient to demonstrate coherent superpositions…
Density of states in a superconductor carrying a supercurrent
A. Anthore, H. Pothier, D. Esteve
We have measured the tunneling density of states (DOS) in a superconductor carrying a supercurrent or exposed to an external magnetic field. The pair correlations are weakened by t…
Dephasing of Electrons in Mesoscopic Metal Wires
F. Pierre, A. B. Gougam, A. Anthore +3
We have extracted the phase coherence time of electronic quasiparticles from the low field magnetoresistance of weakly disordered wires made of silver, copper and gold. In sa…
