Braiding of Majorana zero modes — •Stephan Rachel — School of Physics, University of Melbourne, Australia

There has been tremendous experimental progress in recent years in establishing magnet-superconductor hybrid (MSH) systems as a promising platform for Majorana physics.

In the first part of this talk, I will discuss MSH structures with Re or Nb as a superconducting substrate, and Fe or Mn as magnetic adatoms. In particular, I will illustrate the theoretical challenges to simulate and understand the topological superconductivity and their concomitant Majorana modes in such materials

In the second part of this talk, I will explain our first steps to investigate the braiding of Majorana zero modes. In particular, I will focus on braiding errors which can be introduced from sources such as quasiparticle poisoning and Majorana hybridization, and how these error rates behave in a full quasiparticle background.
