High fidelity measurement of singlet-triplet states in a quantum dot
T. Meunier, K-J. Tielrooij, I. T. Vink +5
We demonstrate experimentally a read-out method that distinguishes between two-electron spin states in a quantum dot. This scheme combines the advantages of the two existing mechan…
Experimental signature of phonon-mediated spin relaxation
T. Meunier, I. T. Vink, L. H. Willems van Beveren +7
We observe an experimental signature of the role of the phonons in spin relaxation between triplet and singlet states in a two-electron quantum dot. Using both the external magneti…
Decoherence and single electron charging in an electronic Mach-Zehnder interferometer
L. V. Litvin, H. -P. Tranitz, W. Wegscheider +1
We investigate the temperature and voltage dependence of the quantum interference in an electronic Mach-Zehnder interferometer using edge channels in the integer quantum-Hall-regim…
A double-dot quantum ratchet driven by an independently biased quantum point contact
V. S. Khrapai, S. Ludwig, J. P. Kotthaus +2
We study a double quantum dot (DQD) coupled to a strongly biased quantum point contact (QPC), each embedded in independent electric circuits. For weak interdot tunnelling we observ…
Non-destructive measurement of electron spins in a quantum dot
T. Meunier, I. T. Vink, L. H. Willems van Beveren +5
We propose and implement a non-destructive measurement that distinguishes between two-electron spin states in a quantum dot. In contrast to earlier experiments with quantum dots, t…
