fault tolerance

Who we are
At neQxt, we build full-stack ion-trap quantum computers, striving for excellent performance and scalability. With decades of expertise in ion-trap technology, neQxt was spun out of Mainz University, and it is headquartered in Germany’s Frankfurt Metropolitan area. Our team of leading talent from Europe and beyond covers the entire value chain, from the basic hardware to end-user software level. Join our passionate team of ambitious scientists, engineers, technicians and quantum enthusiasts, building top-tier fault-tolerant quantum computers together!

TCG CREST – TCG Centres for Research and Education in Science and Technology aspires to be a world-leading research institute in the area of science and technology.

We invite experienced researchers in quantum computing to join us as Visiting Researchers for focused, short-term collaborations aimed at advancing our work in fault-tolerant quantum computing. This opportunity is designed for scientists who wish to contribute intensively to a defined project over a limited residency period. You will work alongside our core research team on topics such as quantum algorithms, quantum error correction, and co-designing scalable architectures across leading platforms (e.g., trapped ions, superconducting qubits, neutral atoms). The position is time-limited and outcome-driven — suited for accomplished individuals who can rapidly engage with complex research challenges and deliver tangible results in a condensed timeframe

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.

At neQxt, our theory team explores the principles that make scalable quantum computing possible. We focus on logical-qubit systems: developing quantum error correcting codes, decoding methods, and logical gate constructions, and studying the mathematical structures that underlie them. Our work aims to deepen the understanding of how fragile quantum information can be preserved over long timescales and across large systems. By advancing the theoretical foundations of quantum fault tolerance, we contribute to both the science of quantum information and the long-term vision of reliable quantum computing.
