InAs-Al Hybrid Devices Passing the Topological Gap Protocol
Morteza Aghaee, Arun Akkala, Zulfi Alam +124
We present measurements and simulations of semiconductor-superconductor heterostructure devices that are consistent with the observation of topological superconductivity and Majora…
Comparing tunneling spectroscopy and charge sensing of Andreev bound states in a semiconductor-superconductor hybrid nanowire structure
Deividas Sabonis, David van Zanten, Judith Suter +7
Transport studies of Andreev bound states (ABSs) are complicated by the interplay of charging effects and superconductivity. Here, we compare transport approaches to ABS spectrosco…
Quantum-Dot Parity Effects in Trivial and Topological Josephson Junctions
D. Razmadze, E. C. T. O'Farrell, P. Krogstrup +1
An odd-occupied quantum dot in a Josephson junction can flip transmission phase, creating a π-junction. When the junction couples topological superconductors, no phase flip is expe…
Dispersive sensing in hybrid InAs/Al nanowires
Deividas Sabonis, Eoin C. T. O'Farrell, Davydas Razmadze +4
Dispersive charge sensing is realized in hybrid semiconductor-superconductor nanowires in gate-defined single- and double-island device geometries. Signal-to-noise ratios (SNRs) we…
Photon Assisted Tunneling of Zero Modes in a Majorana Wire
David M. T. van Zanten, Deividas Sabonis, Judith Suter +8
Hybrid nanowires with proximity-induced superconductivity in the topological regime host Majorana zero modes (MZMs) at their ends, and networks of such structures can produce topol…
Radio-frequency methods for Majorana-based quantum devices: fast charge sensing and phase diagram mapping
Davydas Razmadze, Deividas Sabonis, Filip K. Malinowski +9
Radio-frequency (RF) reflectometry is implemented in hybrid semiconductor-superconductor nanowire systems designed to probe Majorana zero modes. Two approaches are presented. In th…
