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…
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…
Zeeman energy and spin relaxation in a one-electron quantum dot
R. Hanson, B. Witkamp, L. M. K. Vandersypen +3
We have measured the relaxation time, T1, of the spin of a single electron confined in a semiconductor quantum dot (a proposed quantum bit). In a magnetic field, applied parallel t…
