Machine-learned tuning of artificial Kitaev chains from tunneling-spectroscopy measurements
Jacob Benestad, Athanasios Tsintzis, Rubén Seoane Souto +3
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 that…
Josephson junction π-0 transition induced by orbital hybridization in a double quantum dot
Rousan Debbarma, Athanasios Tsintzis, Markus Aspegren +5
In this work, we manipulate the phase shift of a Josephson junction using a parallel double quantum dot (QD). By employing a superconducting quantum interference device, we determi…
Probing Majorana localization in minimal Kitaev chains through a quantum dot
Rubén Seoane Souto, Athanasios Tsintzis, Martin Leijnse +1
Artificial Kitaev chains, formed by quantum dots coupled via superconductors, have emerged as a promising platform for realizing Majorana bound states. Even a minimal Kitaev chain…
Roadmap towards Majorana qubits and nonabelian physics in quantum dot-based minimal Kitaev chains
Athanasios Tsintzis, Rubén Seoane Souto, Karsten Flensberg +2
The possibility to engineer artificial Kitaev chains in arrays of quantum dots coupled via narrow superconducting regions has emerged as an attractive way to overcome the disorder…
Creating and detecting poor man's Majorana bound states in interacting quantum dots
Athanasios Tsintzis, Rubén Seoane Souto, Martin Leijnse
We propose and theoretically investigate an alternative way to create the poor man's Majorana bound states (MBSs) introduced in Phys. Rev. B 86, 134528 (2012). Our proposal is base…
Band structure and end states in InAs/GaSb core-shell-shell nanowires
Florinda Viñas Boström, Athanasios Tsintzis, Michael Hell +1
Quantum wells in InAs/GaSb heterostructures can be tuned to a topological regime associated with the quantum spin Hall effect, which arises due to an inverted band gap and hybridiz…
