Majorana modes in quantum dots coupled via a floating superconducting island

Year: 2025

Type: article

Abstract: The authors investigate here Majorana modes in quantum dots, coupled via a floating superconducting island with charging energy. They identify Majorana sweet spots away from charge-degeneracy points. This finding opens routes for engineering interacting topological devices based on hybrid quantum dot--superconductor platforms that can reveal unique Majorana properties, including electron teleportation and topological Kondo effect.
