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…
Hole spin in tunable Ge hut wire double quantum dot
Gang Xu, Fei Gao, Ke Wang +8
Holes in germanium (Ge) exhibit strong spin-orbit interaction, which can be exploited for fast and all-electrical manipulation of spin states. Here, we report transport experiments…
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…
Dipole coupling of a tunable hole double quantum dot in germanium hut wire to a microwave resonator
Gang Xu, Yan Li, Fei Gao +8
The germanium (Ge) hut wire system has strong spin-orbit coupling, a long coherence time due to a very large heavy-light hole splitting, and the advantage of site-controlled large-…
