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…

Four-Majorana qubit with charge readout: dynamics and decoherence
Tommy Li, William A. Coish, Michael Hell +2
We present a theoretical analysis of a Majorana-based qubit consisting of two topological superconducting islands connected via a Josephson junction. The qubit is operated by elect…

Hybridization of sub-gap states in one-dimensional superconductor/semiconductor Coulomb islands
E. C. T. O'Farrell, A. C. C. Drachmann, M. Hell +10
We present measurements of one-dimensional superconductor-semiconductor Coulomb islands, fabricated by gate confinement of a two-dimensional InAs heterostructure with an epitaxial…
