Enhanced intrinsic spin-orbit driving of a Loss-DiVincenzo qubit near the spin-valley hotspot in Si/SiGe
Alexander Willmes, Max Oberländer, Max Beer +7
In most Si/SiGe-based spin qubit implementations, high-fidelity single-qubit gates are achieved using micromagnets, which enable the use of electric spin dipole resonance via synth…

Exchange interaction in gate-defined quantum dots beyond the Hubbard model
Alexander Willmes, Patrick Bethke, M. Mohamed El Kordy Shehata +10
A quantitative description of the exchange interaction in quantum dots is relevant for modeling gate operations of spin qubits. By measuring the amplitude and frequency of exchange…
