Senior Quantum Information Scientist (Error Correction)

Quandela

Massy or Paris, France

As a Senior Quantum Error Correction Researcher, you will shape the development of Quandela’s fault-tolerant quantum computing architecture.

Your work will directly influence our long-term roadmap and contribute to the robustness and scalability of our photonic quantum hardware.

In this role, you will contribute to key milestones of our FTQC roadmap, working closely with Quandela’s research and engineering teams and an extended network of academic partners (INRIA Paris, LIP6 – Sorbonne Université, INRIA Saclay, Institut de Mathématiques de Bordeaux…).

What You’ll Do

You will lead the design and performance analysis of fault-tolerant protocols adapted to our spin-photon systems. Your contributions will support both near-term experiments and long-term system scaling.

Initial scope includes:

• Provide guidance on QEC codes: oversee the simulation and analysis of stabilizer, dynamical, and good qLDPC code families under realistic device constraints;
• Improve FTQC strategies: Develop fault-tolerant protocols suited to Quandela’s hardware and error model;
• Benchmark decoders: Design custom decoding methods and guide integration based on speed vs accuracy tradeoffs;
• Collaborate across domains: Work closely with hardware and software teams to model errors, improve simulations, and design QEC experiments.

At Quandela, your research will influence prototypes, inform system architecture, and directly support our FTQC roadmap. Because our work is embedded in a strong academic ecosystem, your contributions will also resonate through publications, conference talks, and international collaborations.

Requirements

Ideal Profile:

This position is well-suited for a scientist who combines deep theoretical training with a desire to see ideas translated into real, scalable platforms.

• PhD in Physics, Mathematics, Computer Science or a related field, with a specialisation in Quantum Error Correction;
• 5+ years of post-doctoral research experience, in academia or industry;
• Solid experience with simulation tools (e.g. STIM, decoder implementations);
• Track record of scientific publications in QEC/FTQC;
• Fluent in English (French is optional, not required);
• Willingness to collaborate across sites and engage with Paris based teams when needed;
• Familiarity with photonic architectures is appreciated.
