Excited-state spectroscopy on a nearly-closed quantum dot via charge detection
J. M. Elzerman, R. Hanson, L. H. Willems van Beveren +2
We demonstrate a novel method for measuring the discrete energy spectrum of a quantum dot connected very weakly to a single lead. A train of voltage pulses applied to a metal gate…
Single-electron charging and detection in a laterally-coupled quantum dot circuit in the few-electron regime
L. -X. Zhang, P. Matagne, J. P. Leburton +2
We provide a physical analysis of the charging and detection of the first few electrons in a laterally-coupled GaAs/AlGaAs quantum dot (LCQD) circuit with integrated quantum point…
Semiconductor few-electron quantum dot operated as a bipolar spin filter
R. Hanson, L. M. K. Vandersypen, L. H. Willems van Beveren +3
We study the spin states of a few-electron quantum dot defined in a two-dimensional electron gas, by applying a large in-plane magnetic field. We observe the Zeeman splitting of th…
Measurement efficiency and n-shot read out of spin qubits
Hans-Andreas Engel, Vitaly Golovach, Daniel Loss +4
We consider electron spin qubits in quantum dots and define a measurement efficiency e to characterize reliable measurements via n-shot read outs. We propose various implementation…
