Strong spin-orbit interaction and -factor renormalization of hole spins in Ge/Si nanowire quantum dots
F. N. M. Froning, M. J. Rančić, B. Hetényi +8
The spin-orbit interaction lies at the heart of quantum computation with spin qubits, research on topologically non-trivial states, and various applications in spintronics. Hole sp…

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…

Single, double, and triple quantum dots in Ge/Si nanowires
F. N. M. Froning, M. K. Rehmann, J. Ridderbos +6
We report highly tunable control of holes in Ge/Si core/shell nanowires (NWs). We demonstrate the ability to create single quantum dots (QDs) of various sizes, with low hole occupa…
