Benchmarking low-power flopping-mode spin qubit fidelities in Si/SiGe devices with alloy disorder
Steve M. Young, Mitchell Brickson, Jason R. Petta +1
In the "flopping-mode" regime of electron spin resonance, a single electron confined in a double quantum dot is electrically driven in the presence of a magnetic field gradient. Th…

Using a high-fidelity numerical model to infer the shape of a few-hole Ge quantum dot
Mitchell Brickson, N. Tobias Jacobson, Andrew J. Miller +4
The magnetic properties of hole quantum dots in Ge are sensitive to their shape due to the interplay between strong spin-orbit coupling and confinement. We show that the split-off…
