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…
Coherence times of dressed states of a superconducting qubit under extreme driving
C. M. Wilson, T. Duty, F. Persson +3
In this work, we measure longitudinal dressed states of a superconducting qubit, the single Cooper-pair box, and an intense microwave field. The dressed states represent the hybrid…
Observation of quantum capacitance in the Cooper-pair transistor
T. Duty, G. Johansson, K. Bladh +3
We have fabricated a Cooper-pair transistor (CPT) with parameters such that for appropriate voltage biases, the sub-gap charge transport takes place via slow tunneling of quasipart…
