The poor man's Majorana tetron
Maximilian Nitsch, Lorenzo Maffi, Virgil V. Baran +4
The Majorana tetron is a prototypical topological qubit stemming from the ground state degeneracy of a superconducting island hosting four Majorana modes. This degeneracy manifests…
Majorana modes in quantum dots coupled via a floating superconducting island
R. Seoane Souto, V. V. Baran, M. Nitsch +4
Majorana modes can be engineered in arrays where quantum dots (QDs) are coupled via grounded superconductors, effectively realizing an artificial Kitaev chain. Minimal Kitaev chain…
Spin-1 Haldane chains of superconductor-semiconductor hybrids
Virgil V. Baran, Jens Paaske
We theoretically explore the possibility of realizing the symmetry-protected topological Haldane phase of spin-1 chains in a tunable hybrid platform of superconducting islands (SIs…
BCS surrogate models for floating superconductor-semiconductor hybrids
Virgil V. Baran, Jens Paaske
Superconductor-semiconductor hybrid devices, involving quantum dots interfaced with floating and/or grounded superconductors, have reached a level of complexity which calls for the…
