Senior quantum information scientist

Summary

Join Quandela's Fault-Tolerant Quantum Computing (FTQC) team and shape the development of their fault-tolerant quantum computing architecture. As a senior Quantum Error Correction researcher, you will lead the design and performance analysis of fault-tolerant protocols adapted to their spin-photon systems, contributing to both near-term experiments and long-term system scaling. Your responsibilities include providing guidance on QEC codes, improving FTQC strategies, benchmarking decoders, and collaborating with hardware and software teams. This role requires a PhD in a relevant field, 4+ years of post-doctoral research experience, solid experience with simulation tools, and a publication record in QEC/FTQC. The ideal candidate possesses deep theoretical training and a desire to translate ideas into real, scalable platforms. Quandela offers flexible hours, remote work, profit-sharing, a company savings plan, and various other benefits.

Requirements

• PhD in Physics, Mathematics, Computer Science or a related field, with a specialisation in Quantum Error Correction
• 4+ 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)

Responsibilities

• 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
• 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

Preferred Qualifications

Familiarity with photonic architectures is appreciated; interest in experimental interaction is a plus

Benefits

• 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)
• Meal subsidies (Swile)
