Senior Researcher Fault-Tolerant Quantum Computing

Company OverviewneQxt is a trailblazing company at the forefront of quantum computing technology. With decades of expertise in ion-trap technology, neQxt was founded at Johannes Gutenberg University Mainz, Germany, emerging from the renowned research group of Prof. Dr. Ferdinand Schmidt-Kaler. At neQxt, our theory team explores the principles that make scalable quantum computing possible. We study how fault tolerance can be realized under realistic conditions, designing circuits, developing simulation methods, and analyzing noise at the circuit level. A key part of our work is to understand trade-offs between different approaches and how they can be embedded into modular architectures. We aim to connect theoretical insights with practical feasibility, developing techniques that move fault tolerance closer to realization. By building tools, models, and architectures, we provide a bridge between abstract principles and the requirements of physical quantum processors.
