Spin-mixing enhanced proximity effect in aluminum-based superconductor-semiconductor hybrids
G. P. Mazur, N. van Loo, J. Y. Wang +13
In superconducting quantum circuits, aluminum is one of the most widely used materials. It is currently also the superconductor of choice for the development of topological qubits.…
Electronic Structure and Epitaxy of CdTe Shells on InSb Nanowires
Ghada Badawy, Bomin Zhang, Tomáš Rauch +10
Indium antimonide (InSb) nanowires are used as building blocks for quantum devices because of their unique properties, i.e., strong spin-orbit interaction and large Landé g-factor.…
Triple Andreev dot chains in semiconductor nanowires
Hao Wu, Po Zhang, John P. T. Stenger +6
Kitaev chain is a theoretical model of a one-dimensional topological superconductor with Majorana zero modes at the two ends of the chain. With the goal of emulating this model, we…
Hysteretic magnetoresistance in nanowire devices due to stray fields induced by micromagnets
Y. Jiang, E. J. de Jong, V. van de Sande +4
We study hysteretic magnetoresistance in InSb nanowires due to stray magnetic fields from CoFe micromagnets. Devices without any ferromagnetic components show that the magnetoresis…
Spin transport in ferromagnet-InSb nanowire quantum devices
Zedong Yang, Brett Heischmidt, Sasa Gazibegovic +5
Signatures of Majorana zero modes (MZMs), which are the building blocks for fault-tolerant topological quantum computing, have been observed in semiconductor nanowires (NW) with st…
Erasing odd-parity states in semiconductor quantum dots coupled to superconductors
Z. Su, R. Zitko, P. Zhang +9
Quantum dots are gate-defined within InSb nanowires, in proximity to NbTiN superconducting contacts. As the coupling between the dot and the superconductor is increased, the odd-pa…
