Job Description:

Join the Fault-Tolerant Quantum Computing (FTQC) team within Quandela’s Scalable Architecture division - where theory is developed in collaboration with experimental research and systems engineering teams to advance scalable photonic quantum computing.

As a senior Quantum Error Correction researcher, you will shape the development of our fault-tolerant quantum computing architecture. Your insights will guide the evolution of our long-term roadmap and contribute to the robustness and scalability of Quandela’s cutting-edge hardware.

Why Join Quandela ?

Quandela is a deep-tech quantum company based in Paris-Saclay, with strong academic roots (CNRS/C2N) and a mission to develop large-scale quantum computers. We're at the forefront of photonic quantum computing, combining scientific investigation with a strong engineering mindset. Our R&D spans the full quantum computing stack—from quantum device fabrication to system-level control and quantum software.

In this role, you will contribute to key milestones for our FTQC roadmap, while collaborating with our in-house experts and our extended network of academic partners (INRIA Paris, LIP6 – Sorbonne Université, INRIA Saclay, Institut de Mathématiques de Bordeaux…). You will join a team committed to delivering meaningful advances in quantum error correction - both in theory and in its implementation on real photonic systems.

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 work will influence prototypes, inform system architecture, and directly support our FTQC roadmap. And, because our research efforts are embedded in a broader ecosystem of peer-reviewed publications and international academic partnerships, your contributions will resonate across the community—through publications, conference talks, and collaborations that help define the future of fault-tolerant quantum computing.

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.
• 3+ 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).
• Familiarity with photonic architectures is appreciated; interest in experimental interaction is a plus.
• Flexible hours and remote working
• Profit-sharing and a company savings plan
• Public transport subscription covered at 50%
• Annual sustainable mobility bonus for eco-friendly transport (e-bike, e-scooter, electric car)
• Fully covered health insurance (Alan)
• Referral program (€1,000 for a junior candidate and €2,000 for an experienced candidate)
• Access to a nursery via choisir-ma-creche or contribution to childcare expenses
• Subsidy for gym membership and sports activities (Gymlib)

At Quandela, we value intellectual diversity, curiosity, and initiative. If you’re passionate about QEC and see yourself contributing - even if you don’t meet every listed requirement - we’d love to hear from you. If you're driven by challenge and inspired by the future of quantum computing, let's talk.
