Tolerance of Majorana Teleportation in Mesoscopic Topological Superconductors

We investigate teleportation interference associated with the non-local character of Majorana zero modes (MZMs) as a probe of MZMs focusing on the tolerance of teleportation against disturbances, such as inhomogeneous potentials at junctions and disorder.We develop a method for calculating non-local conductance in mesoscopic topological superconductors with fixed parity.In the trivial phase, the non-local conductance exhibits the h/2e-periodicity, while in the topological phase with fixed parity, it exhibits the h/e-periodicity, indicative of Majorana teleportation.We find that the h/e-periodicity is stable against changes in inhomogeneous potential structures and disorder.These results imply that MZMs can cause teleportation interference even in the presence of disturbances, leading to a clear distinction between the trivial and topological phases.
