We are looking for a Quantum Error Correction Engineer. In this role, you turn quantum error correction theory into practical building blocks for fault-tolerant quantum computing. You will help design, analyze, and implement error-correcting codes and decoding algorithms that pave the way for scalable fault-tolerant quantum computing architectures. Your work connects theory with hardware reality and plays a central role in shaping how our quantum processors scale reliably. The position is based in Munich, Germany.
What will I be doing?
- Develop and analyze quantum error-correcting codes with realistic connectivity and hardware constraints
- Design and evaluate fault-tolerant operations, including multi-qubit logical gate strategies such as lattice surgery
- Contribute to fault-tolerant quantum algorithms and algorithm-specific error correction approaches
- Design, benchmark, and improve decoding algorithms, including: graph-based decoders (belief propagation, union-find, minimum-weight perfect matching) and machine-learning-based decoding approaches
- Implement and optimize decoding algorithms in Python, C/C++, or Rust, with potential deployment on FPGA platforms
- Perform resource estimation and scalability analysis for error-corrected architectures
- Collaborate closely with hardware, control, and software teams to ensure alignment between error correction strategies and real QPU capabilities
- Publish and present high-impact research results in leading scientific journals and conferences
- Maintain high internal and external code quality standards, ensuring scalability and long-term maintainability
