Qubit ZooClean-device theory for optimizing planar semiconductor-superconductor Josephson junctions by narrowing the superconducting strips and tuning the electrostatic potential in the uncovered region.
Key Results
- Predicts an optimal superconducting-strip width of roughly 100–200 nm over the studied parameter range.
- Finds clean-device topological gaps as large as about 40% of the parent superconducting gap.
- Presents an engineering target rather than an experimental Majorana or qubit demonstration.
