Coherent and ultra-low-power EDSR with a flopping-mode spin qubit in germanium

Alexei Orekhov, Wonjin Jang, Pan Zhang +13

Hole spin qubits in semiconductor quantum dots (QDs) enable high-fidelity all-electric control, but conventional electric dipole spin resonance (EDSR) can require substantial rf dr…

Disentangling orbital and confinement contributions to -factor in Ge/SiGe hole quantum dots

L. Sommer, I. Seidler, F. J. Schupp +12

Spin qubits are typically operated in the lowest orbital of a quantum dot to minimize interference from nearby states. In valence-band hole systems, strong spin-orbit coupling link…
