Are pinholes the cause of excess current in superconducting tunnel junctions? A study of Andreev current in highly resistive junctions
Tine Greibe, Markku P. V. Stenberg, C. M. Wilson +3
In highly resistive superconducting tunnel junctions, excess subgap current is usually observed and is often attributed to microscopic "pinholes" in the tunnel barrier. We have stu…
Fast readout of a single Cooper-pair box using its quantum capacitance
F. Persson, C. M. Wilson, M. Sandberg +1
We have fabricated a single Cooper-pair box (SCB) together with an on-chip lumped element resonator. By utilizing the quantum capacitance of the SCB, its state can be read out by d…
The Josephson Bifurcation Amplifier for Quantum Measurements
I. Siddiqi, R. Vijay, F. Pierre +5
We have constructed a new type of amplifier whose primary purpose is the readout of superconducting quantum bits. It is based on the transition of an RF-driven Josephson junction b…
