Ultrafast and Electrically Tunable Rabi Frequency in a Germanium Hut Wire Hole Spin Qubit
He Liu, Ke Wang, Fei Gao +9
Hole spin qubits based on germanium (Ge) have strong tunable spin orbit interaction (SOI) and ultrafast qubit operation speed. Here we report that the Rabi frequency (f_Rabi) of a…
Exploring Spin AGP Ansatze for Strongly Correlated Spin Systems
Zhiyuan Liu, Fei Gao, Guo P. Chen +3
The antisymmetrized geminal power (AGP), a wave function equivalent to number-projected Hartree--Fock--Bogoliubov (HFB), and number-projected Bardeen--Cooper--Schrieffer (BCS) when…
Quantum Interference and Coherent Population Trapping in a Double Quantum Dot
Yuan Zhou, Ke Wang, He Liu +5
Quantum interference is a natural consequence of wave-particle duality in quantum mechanics, and is widely observed at the atomic scale. One interesting manifestation of quantum in…
Gate-Tunable Spin-Orbit Coupling in a Germanium Hole Double Quantum Dot
He Liu, Ting Zhang, Ke Wang +10
Hole spins confined in semiconductor quantum dot systems have gained considerable interest for their strong spin-orbit interactions (SOIs) and relatively weak hyperfine interaction…
Anisotropic g-Factor and Spin-Orbit Field in a Ge Hut Wire Double Quantum Dot
Ting Zhang, He Liu, Fei Gao +9
Holes in nanowires have drawn significant attention in recent years because of the strong spin-orbit interaction, which plays an important role in constructing Majorana zero modes…
Ultrafast coherent control of a hole spin qubit in a germanium quantum dot
Ke Wang, Gang Xu, Fei Gao +13
Operation speed and coherence time are two core measures for the viability of a qubit. Strong spin-orbit interaction (SOI) and relatively weak hyperfine interaction make holes in g…
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-…
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…
