Quantum dots investigated with charge detection techniques
T. Ihn, Simon Gustavsson, Urszula Gasser +7
The detection of the quantum dot charge state using a quantum point contact charge detector has opened a new exciting route for the investigation of quantum dot devices in recent y…
Noise-induced spectral shift measured in a Double Quantum Dot
Bruno Küng, Simon Gustavsson, Theodore Choi +6
We measure the shot noise of a quantum point-contact using a capacitively coupled InAs double quantum dot as an on-chip sensor. Our measurement signals are the (bidirectional) inte…
Time-resolved charge detection with cross-correlation techniques
B. Küng, O. Pfäffli, S. Gustavsson +4
We present time-resolved charge sensing measurements on a GaAs double quantum dot with two proximal quantum point contact (QPC) detectors. The QPC currents are analyzed with cross-…
Statistical electron excitation in a double quantum dot induced by two independent quantum point contacts
U. Gasser, S. Gustavsson, B. Küng +4
We investigate experimentally the influence of current flow through two independent quantum point contacts to a nearby double quantum dot realized in a GaAs-AlGaAs heterostructure.…
