Spin qubit shuttling between coupled quantum dots with inhomogeneous Landé g-tensors
Zhi-Hai Liu, Xiao-Fei Liu, H. Q. Xu
By utilizing the site-dependent spin quantization axis in semiconductor quantum dot (QD) arrays, shuttling-based spin qubit gates have become an appealing approach to realize scala…
Laughlin charge pumping from interplay of chiral Dirac and chiral Majorana modes
Zhan Cao, Yang Feng, Zhi-Hai Liu +1
Laughlin charge pumping has provided critical insights into the topological classification of individual materials, but remains largely unexplored in topological junctions. We expl…
One-dimensional quantum dot array integrated with charge sensors in an InAs nanowire
Yi Luo, Xiao-Fei Liu, Zhi-Hai Liu +8
We report an experimental study of a one-dimensional quintuple-quantum-dot array integrated with two quantum dot charge sensors in an InAs nanowire. The device is studied by measur…
Coupling of quantum-dot states via elastic-cotunneling and crossed Andreev reflection in a minimal Kitaev chain
Zhi-Hai Liu, Chuanchang Zeng, H. Q. Xu
Recently, exciting progress has been made in using the superconducting nanowires coupled to gate-defined quantum dots (QDs) to mimic the Kiteav chain and realize the Majorana-bound…
Multi-qubit DC gates over an inhomogeneous array of quantum dots
Jiaan Qi, Zhi-Hai Liu, Hongqi Xu
The prospect of large-scale quantum computation with an integrated chip of spin qubits is imminent as technology improves. This invites us to think beyond the traditional 2-qubit-g…
Scattering description of edge states in Aharonov-Bohm triangle chains
Zhi-Hai Liu, O. Entin-Wohlman, A. Aharony +2
Scattering theory has been suggested as a convenient method to identify topological phases of matter, in particular of disordered systems for which the Bloch band-theory approach i…
