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…
Stark effect spectroscopy of mono- and few-layer MoS
Julian Klein, Jakob Wierzbowski, Armin Regler +5
We demonstrate electrical control of the A-exciton interband transition in mono- and few-layer crystals embedded into photocapacitor devices via the DC Stark effect. Elec…
20 Second Parity Lifetime in an InAs--Pb Tetron Device
Morteza Aghaee, Zulfi Alam, Mariusz Andrzejczuk +162
A central promise of topological quantum computing is that increasing the excitation gap improves device performance significantly. Here, we experimentally validate this principle…
Interferometric Single-Shot Parity Measurement in an InAs-Al Hybrid Device
Morteza Aghaee, Alejandro Alcaraz Ramirez, Zulfi Alam +159
The fusion of non-Abelian anyons or topological defects is a fundamental operation in measurement-only topological quantum computation. In topological superconductors, this operati…
Response to recent comments on Phys. Rev. B 107, 245423 (2023) and Subsection S4.3 of the Supp. Info. for Nature 638, 651-655 (2025)
Morteza Aghaee, Zulfi Alam, Mariusz Andrzejczuk +127
The topological gap protocol (TGP) is a statistical test designed to identify a topological phase with high confidence and without human bias. It is used to determine a promising p…
Ultrathin catalyst-free InAs nanowires on silicon with distinct 1D sub-band transport properties
Fabio del Giudice, Jonathan Becker, Claudio de Rose +6
Ultrathin InAs nanowires (NW) with one-dimensional (1D) sub-band structure are promising materials for advanced quantum-electronic devices, where dimensions in the sub-30 nm diamet…
Model- and Acceleration-based Pursuit Controller for High-Performance Autonomous Racing
Jonathan Becker, Nadine Imholz, Luca Schwarzenbach +3
Autonomous racing is a research field gaining large popularity, as it pushes autonomous driving algorithms to their limits and serves as a catalyst for general autonomous driving.…
