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-…

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…
