Majorana quasiparticles exhibit exotic non-Abelian statistics, that is crucial for the realization of topological quantum bits. The authors demonstrate theoretically that Majoranas can be hosted at a grain-boundary lattice defect immersed in a parent topological superconductor and externally controlled by a magnetic field, which opens a route to defect-based platforms in quantum information technology.
