Quantum interference and phonon-mediated back-action in lateral quantum dot circuits
G. Granger, D. Taubert, C. E. Young +11
Spin qubits have been successfully realized in electrostatically defined, lateral few-electron quantum dot circuits. Qubit readout typically involves spin to charge information con…
Radio frequency pulsed-gate charge spectroscopy on coupled quantum dots
D. Harbusch, S. Manus, H. P. Tranitz +2
Time-resolved electron dynamics in coupled quantum dots is directly observed by a pulsed-gate technique. While individual gate voltages are modulated with periodic pulse trains, av…
Phonon-mediated vs. Coulombic Back-Action in Quantum Dot circuits
D. Harbusch, D. Taubert, H. P. Tranitz +2
Quantum point contacts (QPCs) are commonly employed to capacitively detect the charge state of coupled quantum dots (QD). An indirect back-action of a biased QPC onto a double QD l…
A Schottky top-gated two-dimensional electron system in a nuclear spin free Si/SiGe heterostructure
J. Sailer, V. Lang, G. Abstreiter +8
We report on the realization and top-gating of a two-dimensional electron system in a nuclear spin free environment using 28Si and 70Ge source material in molecular beam epitaxy. E…
Telegraph Noise in Coupled Quantum Dot Circuits Induced by a Quantum Point Contact
D. Taubert, M. Pioro-Ladrière, D. Schröer +3
Charge detection utilizing a highly biased quantum point contact has become the most effective probe for studying few electron quantum dot circuits. Measurements on double and trip…
