Résumé : In the past decade superconductor-semiconductor hybrids have been studied intensively, with significant efforts towards studying Majorana bound states (MBSs). In this talk I will discuss a relatively new approach to realize MBSs using quantum dot-superconductor hybrids. I will focus on how MBSs can be systematically and reliably engineered in a two-dimensional electron gas by tuning the relative strengths of the different kinds of couplings between the quantum dots [1,2].
