Heavy Hole vs. Light Hole Spin Qubits: A Strain-Driven Study of SiGe/Ge and GeSn/Ge

Autor: Dsouza, Kelvin, Del Vecchio, Patrick, Rotaru, Nicolas, Moutanabbir, Oussama, Vashaee, Daryoosh

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 states, g-factor, Rabi frequency, spin relaxation, and dephasing times.
