Strain engineering of Andreev spin qubits in Germanium
Vittorio Coppini, Patrick Del Vecchio, Antonio L. R. Manesco +4
Planar germanium heterostructures are promising hosts for hybrid quantum devices due to their compatibility with superconductors, low material disorder, and relaxed fabrication con…
Electrically Tuneable Variability in Germanium Hole Spin Qubits
Edmondo Valvo, Michele Jakob, Patrick Del Vecchio +2
Hole spin qubits in planar germanium heterostructures are frontrunners for scalable semiconductor quantum computing. However, their current performance is mostly limited by large d…
Nuclear spin-free 70Ge/28Si70Ge quantum well heterostructures grown on industrial SiGe-buffered wafers
P. Daoust, N. Rotaru, D. Biswas +9
The coherence of hole spin qubits in germanium planar heterostructures is limited by the hyperfine coupling to the nuclear spin bath due to 29Si and 73Ge isotopes. Thus, removing t…
Heavy Hole vs. Light Hole Spin Qubits: A Strain-Driven Study of SiGe/Ge and GeSn/Ge
Kelvin Dsouza, Patrick Del Vecchio, Nicolas Rotaru +2
This work investigates and compares the impact of strain on heavy hole (HH) spin qubits in SiGe/Ge and light hole (LH) spin qubits in GeSn/Ge heterostructures, focusing on energy s…
