Seminar: Minimal Kitaev chains: toward coherent experiments with Majorana states

Topological superconductors, that host Majorana states at the ends, have attracted significant attention in the last decade. These states are promising for quantum information storage and processing. Artificial Kitaev chains in arrays of quantum dots coupled via narrow superconducting regions have emerged as an attractive way to realize Majorana states [1]. In this presentation, I will discuss the status of the field. I will discuss how to measure Majorana states in the system [2] and introduce a route toward quantum coherent experiments using Majoranas, going from qubits [3] to braiding experiments [4].
