Isotropic and Anisotropic g-factor Corrections in GaAs Quantum Dots
Leon C. Camenzind, Simon Svab, Peter Stano +5
We experimentally determine isotropic and anisotropic g-factor corrections in lateral GaAs single-electron quantum dots. We extract the Zeeman splitting by measuring the tunnel rat…
Quantum measurement induces a many-body transition
Michael S. Ferguson, Leon C. Camenzind, Clemens Müller +5
The current revolution in quantum technologies relies on the ability to isolate, coherently control, and measure the state of quantum systems. The act of measurement in quantum mec…
Silicon quantum dot devices with a self-aligned second gate layer
Simon Geyer, Leon C. Camenzind, Lukas Czornomaz +5
We implement silicon quantum dot devices with two layers of gate electrodes using a self-alignment technique, which allows for ultra-small gate lengths and intrinsically perfect la…
Ultrafast Hole Spin Qubit with Gate-Tunable Spin-Orbit Switch
F. N. M. Froning, L. C. Camenzind, O. A. H. van der Molen +4
A key challenge in quantum computation is the implementation of fast and local qubit control while simultaneously maintaining coherence. Qubits based on hole spins offer, through t…
Quantum device fine-tuning using unsupervised embedding learning
N. M. van Esbroeck, D. T. Lennon, H. Moon +8
Quantum devices with a large number of gate electrodes allow for precise control of device parameters. This capability is hard to fully exploit due to the complex dependence of the…
Machine learning enables completely automatic tuning of a quantum device faster than human experts
H. Moon, D. T. Lennon, J. Kirkpatrick +10
Device variability is a bottleneck for the scalability of semiconductor quantum devices. Increasing device control comes at the cost of a large parameter space that has to be explo…
