Self-controlled growth of highly uniform Ge/Si hut wires for scalable qubit devices
Fei Gao, Jian-Huan Wang, Hannes Watzinger +13
Semiconductor nanowires have been playing a crucial role in the development of nanoscale devices for the realization of spin qubits, Majorana fermions, single photon emitters, nano…
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…
Ge hole spin qubit
Hannes Watzinger, Josip Kukučka, Lada Vukušić +5
Holes confined in quantum dots have gained considerable interest in the past few years due to their potential as spin qubits. Here we demonstrate double quantum dot devices in Ge h…
Fast Hole Tunneling Times in Germanium Hut Wires Probed by Single-Shot Reflectometry
Lada Vukušić, Josip Kukučka, Hannes Watzinger +1
Heavy holes confined in quantum dots are predicted to be promising candidates for the realization of spin qubits with long coherence times. Here we focus on such heavy-hole states…
Heavy hole states in Germanium hut wires
Hannes Watzinger, Christoph Kloeffel, Lada Vukušić +11
Hole spins have gained considerable interest in the past few years due to their potential for fast electrically controlled qubits. Here, we study holes confined in Ge hut wires, a…
