Majorana bound states constitute one of the simplest examples of emergent non-Abelian
excitations in condensed matter physics. A toy model proposed by Kitaev shows that such …

Abstract Majorana fermions are spin-1/2 neutral particles that are their own antiparticles and
were initially predicted by Ettore Majorana in particle physics but their observation still …

Cooper pairs occupy the ground state of superconductors and are typically composed of
maximally entangled electrons with opposite spin. In order to study the spin and …

Superconductor/semiconductor hybrid devices have attracted increasing interest in the past
years. Superconducting electronics aims to complement semiconductor technology, while …

Kitaev chains in quantum dot-superconductor arrays are a promising platform for the
realization of topological superconductivity. As recently demonstrated, even a two-site chain …

A short superconducting segment can couple attached quantum dots via elastic cotunneling
(ECT) and crossed Andreev reflection (CAR). Such coupled quantum dots can host …

The possibility of engineering artificial Kitaev chains in arrays of quantum dots coupled via
narrow superconducting regions has emerged as an attractive way to overcome the disorder …
