Exact Multi-Valley Envelope Function Theory of Valley Splitting in Si/SiGe Nanostructures
Lasse Ermoneit, Abel Thayil, Thomas Koprucki +1
Valley splitting in strained Si/SiGe quantum wells is a central parameter for silicon spin qubits and is commonly described with envelope-function and effective-mass theories. Thes…
Numerical simulation of coherent spin-shuttling in a QuBus with charged defects
Nils Ciroth, Arnau Sala, Ran Xue +4
Recent advances in coherent conveyor-mode spin qubit shuttling are paving the way for large-scale quantum computing platforms with qubit connectivity achieved by spin qubit shuttle…
Optimization of Si/SiGe Heterostructures for Large and Robust Valley Splitting in Silicon Qubits
Abel Thayil, Lasse Ermoneit, Lars R. Schreiber +2
Small and device-dependent valley splittings remain a key challenge for electron spin qubits in silicon (Si), directly limiting qubit fidelity, device uniformity, and the scalabili…
Theory of Valley Splitting in Si/SiGe Spin-Qubits: Interplay of Strain, Resonances and Random Alloy Disorder
Abel Thayil, Lasse Ermoneit, Markus Kantner
Electron spin-qubits in silicon-germanium (SiGe) heterostructures are a major candidate for the realization of scalable quantum computers. A critical challenge in strained Si/SiGe…
Bayesian Estimation of Laser Linewidth from Delayed Self-Heterodyne Measurements
Lutz Mertenskötter, Markus Kantner
We present a statistical inference approach to estimate the frequency noise characteristics of ultra-narrow linewidth lasers from delayed self-heterodyne beat note measurements usi…
Accurate evaluation of self-heterodyne laser linewidth measurements using Wiener filters
Markus Kantner, Lutz Mertenskötter
Self-heterodyne beat note measurements are widely used for the experimental characterization of the frequency noise power spectral density (FN-PSD) and the spectral linewidth of la…
