摘要
It is argued that Majorana zero modes in a system of quantum fermions lead to the emergence of stretched quantum states allowing for processes with an actual transfer of electronic material between well- separated points. The problem is formulated in the context of a quasi- realistic and exactly solvable model of a quantum wire embedded in a bulk p- wave superconductor. An explicit computation of the tunnelling amplitude is given.
