InAs-Al Hybrid Devices Passing the Topological Gap Protocol
Morteza Aghaee, Arun Akkala, Zulfi Alam +124
We present measurements and simulations of semiconductor-superconductor heterostructure devices that are consistent with the observation of topological superconductivity and Majora…
Gate-Tunable Transmon Using Selective-Area-Grown Superconductor-Semiconductor Hybrid Structures on Silicon
A. Hertel, M. Eichinger, L. O. Andersen +12
We present a gate-voltage tunable transmon qubit (gatemon) based on planar InAs nanowires that are selectively grown on a high resistivity silicon substrate using III-V buffer laye…
Parity switching in a full-shell superconductor-semiconductor nanowire qubit
O. Erlandsson, D. Sabonis, A. Kringhøj +4
The rate of charge-parity switching in a full-shell superconductor-semiconductor nanowire qubit is measured by directly monitoring the dispersive shift of a readout resonator. At z…
Electrical Properties of Selective-Area-Grown Superconductor-Semiconductor Hybrid Structures on Silicon
A. Hertel, L. O. Andersen, D. M. T. van Zanten +9
We present a superconductor-semiconductor material system that is both scalable and monolithically integrated on a silicon substrate. It uses selective area growth of Al-InAs hybri…
Microwave Sensing of Andreev Bound States in a Gate-Defined Superconducting Quantum Point Contact
Vivek Chidambaram, Anders Kringhøj, Lucas Casparis +11
We use a superconducting microresonator as a cavity to sense absorption of microwaves by a superconducting quantum point contact defined by surface gates over a proximitized two-di…
Andreev Modes from Phase Winding in a Full-shell Nanowire-based Transmon
A. Kringhøj, G. W. Winkler, T. W. Larsen +6
We investigate transmon qubits made from semiconductor nanowires with a fully surrounding superconducting shell. In the regime of reentrant superconductivity associated with the de…
