Identification and mitigation of errors in hole spin qubit readout

High-fidelity readout of spin qubits in semiconductor quantum dots can be achieved by combining a radiofrequency charge sensor with spin-to-charge conversion and Pauli spin blockade. However, reaching high readout fidelities with hole spin qubits remains challenging due to site-dependent spin anisotropies and short...

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

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 drive power at the low magnetic fields that are favorable for qubit coherence and readout. In planar Ge hole spin qubits, this can reach -27 d...
