Quantum computing requires reliable control and braiding of Majorana zero modes. These modes emerge in topological superconductors and enable exceptionally stable quantum operations but are highly sensitive to noise and geometric imperfections. Current architectures depend on multiple nanoscale gates that demand delicate tuning. This invention introduced single-gate, self-tuned nanowire geometry, using tapered quasi-1D topological superconductors, that enables natural formation, movement and braiding of Majorana modes with minimal calibration, providing a scalable and robust platform for topological quantum computation.
