Spatial uniformity of g-tensor and spin-orbit interaction in germanium hole spin qubits
Inga Seidler, Bence Hetényi, Lisa Sommer +12
Holes in Ge/SiGe heterostructures are now a leading platform for semiconductor spin qubits, thanks to the high confinement quality, two-dimensional arrays, high tunability, and lar…

Identifying and mitigating errors in hole spin qubit readout
Eoin Gerard Kelly, Leonardo Massai, Bence Hetényi +14
High-fidelity readout of spin qubits in semiconductor quantum dots can be achieved by combining a radio-frequency (RF) charge sensor together with spin-to-charge conversion and Pau…

Capacitive crosstalk in gate-based dispersive sensing of spin qubits
Eoin G. Kelly, Alexei Orekhov, Nico Hendrickx +8
In gate-based dispersive sensing, the response of a resonator attached to a quantum dot gate is detected by a reflected radio-frequency signal. This enables fast readout of spin qu…
