Disorder signatures emerging at millikelvin temperatures in Si/SiGe field-effect stacks
Lino Visser, Alberto Mistroni, Yuji Yamamoto +9
The performance and scalability of electron spin qubits based on gate-defined quantum-dots in undoped Si/SiGe field-effect stacks remain constrained by disorder originating from th…
Comparison of Origins of Re-Entrant Supercurrents at High In-Plane Magnetic Fields in Planar InAs-Al Josephson Junctions
S. R. Mudi, S. Anupam, V. Mourik +1
Hybrid superconductor-semiconductor systems with large spin-orbit coupling are important platforms for realizing topological or triplet superconductivity. Planar Josephson junction…
High yield, low disorder Si/SiGe heterostructures for spin qubit devices manufactured in a BiCMOS pilot line
Alberto Mistroni, Marco Lisker, Yuji Yamamoto +13
The prospect of achieving fault-tolerant quantum computing with semiconductor spin qubits in Si/SiGe heterostructures relies on the integration of a large number of identical devic…
Anisotropic supercurrent suppression and revivals in a graphene-based Josephson junction under in-plane magnetic fields
Philipp Schmidt, Katarina StanojeviÄ, Kenji Watanabe +4
We report on a tunable Josephson junction formed by a bilayer graphene ribbon encapsulated in WSe with superconducting niobium contacts. We characterize the junction by measure…
