Spin-Orbit Interaction Enabled High-Fidelity Two-Qubit Gates
Jiaan Qi, Zhi-Hai Liu, H. Q. Xu
We study the implications of spin-orbit interaction (SOI) for two-qubit gates (TQGs) in semiconductor spin qubit platforms. SOI renders the exchange interaction governing qubit pai…
Charge states, triple points and quadruple points in an InAs nanowire triple quantum dot revealed by an integrated charge sensor
Weijie Li, Zhihai Liu, Jingwei Mu +4
A serial triple quantum dot (TQD) integrated with a quantum dot (QD) charge sensor is realized from an InAs nanowire via a fine finger-gate technique. The complex charge states and…
Topological charge and spin pumping in a semiconductor nanowire
Zhi-Hai Liu, H. Q. Xu
The adiabatic topological pumping is proposed by periodically modulating a semiconductor nanowire double-quantum-dot chain. We demonstrate that the quantized charge transport can b…
Charge detection of a quantum dot under different tunneling barrier symmetries and bias voltages
Jingwei Mu, Weijie Li, Shaoyun Huang +5
We report on the realization of a coupled quantum dot (QD) system containing two single QDs made in two adjacent InAs nanowires. One QD (sensor QD) is used as a charge sensor to de…
Topological states and interplay between spin-orbit and Zeeman interactions in a spinful Su-Schrieffer-Heeger nanowire
Zhi-Hai Liu, O. Entin-Wohlman, A. Aharony +2
The interplay between the spin-orbit and Zeeman interactions acting on a spinful Su-Schrieffer-Heeger model is studied based on an InAs nanowire subjected to a periodic gate potent…
Highly tunable quadruple quantum dot in a narrow bandgap semiconductor InAs nanowire
Jingwei Mu, Shaoyun Huang, Zhi-Hai Liu +7
Quantum dots (QDs) made from semiconductors are among the most promising platforms for the developments of quantum computing and simulation chips, and have advantages over other pl…
