Josephson squelch filter for quantum nanocircuits
P. Forn-Diaz, R. N. Schouten, W. A. den Braver +2
We fabricated and tested a squelch circuit consisting of a copper powder filter with an embedded Josephson junction connected to ground. For small signals (squelch-ON), the small j…
A cryogenic amplifier for fast real-time detection of single-electron tunneling
I. T. Vink, T. Nooitgedagt, R. N. Schouten +2
We employ a cryogenic High Electron Mobility Transistor (HEMT) amplifier to increase the bandwidth of a charge detection setup with a quantum point contact (QPC) charge sensor. The…
Low-frequency Noise in Josephson Junctions for Superconducting Qubits
J. Eroms, L. C. van Schaarenburg, E. F. C. Driessen +6
We have studied low-frequency resistance fluctuations in shadow-evaporated Al/AlOx/Al tunnel junctions. Between 300 K and 5 K the spectral density follows a 1/f-law. Below 5 K, ind…
Real-time detection of single electron tunneling using a quantum point contact
L. M. K. Vandersypen, J. M. Elzerman, R. N. Schouten +3
We observe individual tunnel events of a single electron between a quantum dot and a reservoir, using a nearby quantum point contact (QPC) as a charge meter. The QPC is capacitivel…
