The experimental search for Majorana bound states relies heavily on transport measurements. The topological properties of these states should, in ideal conditions, lead to a quantization of the conductance. In this talk I will first describe how our understanding of this conductance quantization has changed. In particular, I will discuss how local Andreev bound states due to smooth potentials (quasi-Majoranas) or disorder can mimic all local properties of Majorana bound states – to the extent that even a braiding experiment is thinkable. Finally, I will discuss that non-linear voltage effects are expected to play a significant role in Majorana experiments, and show that they can lead to a seeming violation of fundamental symmetries.

Dr. Michael Wimmer is a theoretical physicist working on Majorana fermions, topological phases of matter and quantum computing. He received his Ph.D from University of Regensburg (Germany) in 2008. After this he moved to the Universiteit Leiden, and worked there as a postdoc with Carlo Beenakker until 2013. In 2013 he became a group leader at TU Delft, was promoted to associate professor in 2020. Since 2013, he leads the Quantum Tinkerer group together with Anton Akhmerov at TU Delft. Since 2017, he also acts as the leader of the topological quantum computation roadmap at QuTech.
