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…
Room-temperature tunnel current amplifier and experimental setup for high resolution electronic spectroscopy in millikelvin STM experiments
H. Le Sueur, P. Joyez
The spectroscopic resolution of tunneling measurements performed with a scanning tunneling microscope is ultimately limited by the temperature at which the experiment is performed.…
Micro-fabricated electromagnetic filters for millikelvin experiments
H. Le Sueur, P. Joyez
In this article we report on the design, fabrication and tests of micro-fabricated broadband filters suitable for proper electromagnetic thermalization of electrical lines connecte…
Superconducting atomic contacts under microwave irradiation
M. Chauvin, P. Vom Stein, H. Pothier +4
We have measured the effect of microwave irradiation on the dc current-voltage characteristics of superconducting atomic contacts. The interaction of the external field with the ac…
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…
