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 …

Computational approaches, such as density functional theory (DFT) in conjunction with
descriptor-based analysis and computational hydrogen electrode, have enabled exploring …

Poor man's Majoranas (PMMs) hold the promise to engineer Majorana bound states in a
highly tunable setup consisting of a chain of quantum dots that are connected via …

We demonstrate reliable machine-learned tuning of quantum-dot-based artificial Kitaev
chains to Majorana sweet spots, using the covariance matrix adaptation algorithm. We show …

Realizing Majorana bound states (MBSs) in short, well-controllable chains of coupled
quantum dots sidesteps the problem of disorder but requires finetuning and does not give …

In this work we consider superconductor-semiconductor hybrids containing both trivial and
Majorana zero modes and explore their signatures in the Majorana polarization. In …

Quantum dot-superconductor arrays have emerged as a new and promising material
platform for realizing Kitaev chains with Majorana zero modes. So far, experiments have …

Artificial Kitaev chains can be used to engineer Majorana bound states (MBSs) in
superconductor-semiconductor hybrids. In this work, we realize a two-site Kitaev chain in a …

Two semiconducting quantum dots (QDs) coupled through a superconductor constitute a
minimal realization of a Kitaev chain with Majorana zero modes (MZMs). Such MZMs can be …

A chain of quantum dots (QDs) coupled via semiconductor-superconductor hybrid regions
can form an artificial Kitaev chain hosting Majorana bound states (MBSs). These zero …
