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 …

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 …

Connecting double quantum dots via a semiconductor-superconductor hybrid segment
offers a platform for creating a two-site Kitaev chain that hosts Majorana zero modes at a …

Artificial Kitaev chains, formed by quantum dots coupled via superconductors, have
emerged as a promising platform for realizing Majorana bound states. Even a minimal …

The proximity effect of superconductivity on confined states in semiconductors gives rise to
various bound states such as Andreev bound states, Andreev molecules, and Majorana zero …

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 …

We consider a quantum-dot (QD) based minimal Kitaev chain model and study the effects of
modulation of QD states on the elastic cotunneling (ECT) and crossed Andreev reflection …
