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 …

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 …

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

We construct two-band effective models describing Majorana edge states in a short Kitaev
chain. We derive an analytical formula for the effective Hamiltonian as a function of model …

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 …

In recent years, experimental advances have made it possible to achieve an unprecedented
degree of control over the properties of subgap bound states in hybrid nanoscale …

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 …

Connecting quantum dots through Andreev bound states in a semiconductor-
superconductor hybrid provides a platform to create a Kitaev chain. Interestingly, in a double …
