Design and Optimization of Spin Dynamics in Ge Quantum Dots: g-Factor Modulation, Geometry-Induced Dephasing Sweet Spots, and Phonon-Induced Relaxation
Simulations of realistic SiGe/Ge gate-defined hole quantum dots identify g-factor modulation, geometry-induced dephasing sweet spots, and B^{-9} phonon relaxation scaling via asymmetric confinement.
