Quantum Error Correction Engineer at IQM Quantum Computers (Munich, Germany)
Job Description
IQM is hiring a Quantum Error Correction Engineer in Munich to design codes that fit real superconducting chips and to build the decoders that read them, including machine-learning approaches alongside the established graph-based ones.

About the quantum error correction engineer role at IQM
- Develop quantum error-correcting codes that work with the connectivity real hardware provides, rather than idealised all-to-all layouts
- Work on lattice surgery and related techniques for operating on logical qubits
- Design, benchmark and improve decoding algorithms, including graph-based decoders such as belief propagation, union-find and minimum-weight perfect matching, and machine-learning-based decoding approaches
- Carry out resource estimation for fault-tolerant architectures
The posting names its decoder families explicitly: belief propagation, union-find and minimum-weight perfect matching on the graph side, and machine-learning-based decoding alongside them. It also mentions that implementation may reach down to FPGA work, since decoding has to keep pace with the chip. The posting does not give a closing date, so the role stays listed until it is filled. Re-check the official posting before you apply.
What IQM Quantum Computers is looking for
- A background in quantum error correction and fault-tolerant quantum computing, typically from a PhD or equivalent research experience
- Programming strength in Python and in C++ or Rust for the parts that must run fast
- Experience benchmarking algorithms honestly, with realistic noise models rather than best-case assumptions
- An understanding of how superconducting hardware constrains the codes you can actually run
Nice to have
- Machine-learning decoders in particular, and experience training them on simulated syndrome data
- FPGA or other real-time implementation experience, since decoders must keep up with the hardware
- Familiarity with lattice surgery and logical compilation
- Publications in quantum error correction

How to prepare for this application
- Compare decoders properly: know the accuracy and speed trade-offs between matching, union-find, belief propagation and learned decoders.
- Respect the clock: be ready to discuss the latency budget a decoder has before backlog builds up.
- Connectivity matters: practise reasoning about codes on a fixed lattice instead of assuming arbitrary qubit pairs.
- Write fast code: the posting asks for C++ or Rust, so bring something performance-critical you have written.
- Estimate resources: prepare a rough physical-to-logical qubit calculation for a code you know well.
