We are seeking Senior Researchers in Fault-Tolerant Quantum Computing to contribute to the development of key components of the fault-tolerant stack. These roles focus on decoders and quantum algorithms at the logical level, addressing how quantum information can be processed reliably in large-scale, error-corrected systems. The positions involve developing and analyzing decoding strategies under realistic noise models, as well as designing and evaluating quantum algorithms within fault-tolerant architectures, including resource estimation and logical-level optimization. The emphasis is on rigorous, hands-on research that advances the performance, scalability, and understanding of error-corrected quantum computation. A central aspect of the role is contributing to the integration of these methods into modular fault-tolerant architectures, ensuring consistency between algorithmic, decoding, and system-level considerations.
Company Overview
neQxt 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.
