Parametric two-qubit gates via Landau-Zener interference
Simon Geisert, Albert Hertel, Soeren Ihssen +23
We propose and demonstrate gates between two superconducting qubits based on quantum interference of consecutive Landau-Zener (LZ) transitions. This gate mechanism bridges between…
Proximitized Topological Insulator Charge Island Fabricated via In Situ Multi-Angle Stencil Lithography
Benedikt Frohn, Tobias Schmitt, Vanessa Serrano +7
Hybrid superconductor-topological insulator (TI) nanostructures constitute a promising material platform for exploring proximity-induced superconductivity in systems with topologic…
On-chip stencil lithography for superconducting qubits
Roudy Hanna, Sören Ihssen, Simon Geisert +22
Improvements in circuit design and more recently in materials and surface cleaning have contributed to a rapid development of coherent superconducting qubits. However, organic resi…
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…
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…
