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…
Distinguishing Majorana bound states from localized Andreev bound states by interferometry
Michael Hell, Karsten Flensberg, Martin Leijnse
Experimental evidence for Majorana bound states (MBSs) is so far mainly based on the robustness of a zero-bias conductance peak. However, similar features can also arise due to And…
Coupling and braiding Majorana bound states in networks defined in proximitized two-dimensional electron gases
Michael Hell, Karsten Flensberg, Martin Leijnse
Two-dimensional electron gases with strong spin-orbit coupling covered by a superconducting layer offer a flexible and potentially scalable platform for Majorana networks. We predi…
Anharmonicity of a Gatemon Qubit with a Few-Mode Josephson Junction
A. Kringhøj, L. Casparis, M. Hell +8
Coherent operation of gate-voltage-controlled hybrid transmon qubits (gatemons) based on semiconductor nanowires was recently demonstrated. Here we experimentally investigate the a…
