Robust Spin Qubit Coupler via Minimal Kitaev Chain
Jiaan Qi, Hongqi Xu
While a minimal Kitaev chain is promised to host unprotected Majorana zero modes, its role for spin qubits is relatively underappreciated. Following recent breakthroughs in the fin…
Supercurrent and multiple Andreev reflections in Ge hut nanowire Josephson Junctions
Han Gao, Jian-Huan Wang, Ji-Yin Wang +2
We report an experimental study of induced superconductivity in Ge hut nanowire Josephson junctions. The Ge hut nanowires are grown on prepatterned SiGe ridges via molecular beam e…
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…
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…
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…
Supercurrent, Multiple Andreev Reflections and Shapiro Steps in InAs Nanosheet Josephson Junctions
Shili Yan, Haitian Su, Dong Pan +8
High-quality free-standing InAs nanosheets are emerging layered semiconductor materials with potentials in designing planar Josephson junction devices for novel physics studies due…
