Exchange anisotropies in microwave-driven singlet-triplet qubits

Jaime Saez-Mollejo, Daniel Jirovec, Yona Schell +7

Hole spin qubits are rapidly emerging as the workhorse of semiconducting quantum processors because of their large spin-orbit interaction, enabling fast all-electric operations at…

Dynamics of hole singlet triplet qubits with large g-factor differences

Daniel Jirovec, Philipp M. Mutter, Andrea Hofmann +8

The spin-orbit interaction is the key element for electrically tunable spin qubits. Here we probe the effect of cubic Rashba spin-orbit interaction on mixing of the spin states by…

Zero field splitting of heavy-hole states in quantum dots

G. Katsaros, J. Kukučka, L. Vukušić +5

Using inelastic cotunneling spectroscopy, we observe a 55μeV zero field splitting in the spin triplet manifold of Ge hut wire quantum dots. The degeneracy of the heavy hole triplet…

Single-shot readout of hole spins in Ge

Lada Vukušić, Josip Kukučka, Hannes Watzinger +3

The strong atomistic spin orbit coupling of holes makes single-shot spin readout measurements difficult because it reduces the spin lifetimes. By integrating the charge sensor into…
