Thermal reconstruction as a method of substrate preparation for highly crystalline superconducting TiN resonators
Thomas J. Smart, Marc Neis, Janine Lorenz +15
High quality crystalline growth of a thin film on sapphire requires sufficient substrate preparation, often achieved via the use of aggressive chemical cleaning. Direct thermal rec…
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 materials platform for exploring proximity-induced superconductivity in systems with topologi…
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…
Frustrated Frustration of Arrays with Four-Terminal Nb-Pt-Nb Josephson Junctions
Justus Teller, Christian Schäfer, Kristof Moors +6
We study the frustration pattern of a square lattice with in-situ fabricated Nb-Pt-Nb four-terminal Josephson junctions. The four-terminal geometry gives rise to a checker board pa…
Fabrication and characterization of InAs nanowire-based quantum dot structures utilizing buried bottom gates
Anton Faustmann, Patrick Liebisch, Benjamin Bennemann +6
Semiconductor nanowires can be utilized to create quantum dot qubits. The formation of quantum dots is typically achieved by means of bottom gates created by a lift-off process. As…
