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…
A dressed singlet-triplet qubit in germanium
Konstantinos Tsoukalas, Uwe von Lüpke, Alexei Orekhov +15
In semiconductor hole spin qubits, low magnetic field () operation extends the coherence time () but proportionally reduces the gate speed. In contrast, singlet-…
Impact of interface traps on charge noise, mobility and percolation density in Ge/SiGe heterostructures
L. Massai, B. Hetényi, M. Mergenthaler +8
Hole spins in Ge/SiGe heterostructure quantum dots have emerged as promising qubits for quantum computation. The strong spin-orbit coupling (SOC), characteristic of heavy-hole stat…
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…
