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 …

We generalize the classical thermal Mpemba effect (where an initially hot system relaxes
faster to the final equilibrium state than a cold one) to open quantum systems coupled to …

The fusion of non-Abelian anyons is a fundamental operation in measurement-only
topological quantum computation. In one-dimensional topological superconductors (1DTSs) …

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 …

InSb, a narrow-band III-V semiconductor, is known for its small bandgap, small electron
effective mass, high electron mobility, large effective g-factor, and strong spin-orbit …

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 …

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

Few-site Kitaev chains are promising for realizing Majorana zero modes without topological
protection but fully nonlocal, which are known as poor man's Majorana modes. While …
