Topological Quantum Espionage

ORAL

Abstract

Can one transfer information encoded in Majorana modes between two distinct platforms? Or must one read out the information before transferring it to a new medium? We explore this question, and find that not only can information be transfered, but in some cases a fermionic occupation number can be stored non-locally by Majorana modes localized in two distinct p-wave superconductors with opposite chirality, as long as some tunneling contact between the two exists.
