Quantum Information Scientist, Quantum Architecture and Performance – Quandela (Hybrid, France)

Assess and shape Quandela’s near- and mid-term photonic quantum-computing architectures. Build models, simulations, and performance analyses for scalable fault-tolerant systems.

Description

  • Assess the capabilities and constraints of near- and mid-term quantum architectures
  • Apply complexity theory, benchmarking, characterisation, and related methods to evaluate architecture designs
  • Account for realistic noise, native operations, and physical limitations in architectural analyses
  • Determine when architectures may deliver useful computational capabilities or quantum advantage
  • Create scientific models and numerical tools to examine architecture and performance trade-offs
  • Analyse how architecture decisions interact with algorithms, resource needs, and quantum error-correction strategies
  • Develop and lead research projects focused on architecture design and performance
  • Collaborate across the Architecture and Algorithms and Applications teams to link physical-layer questions with computational capabilities and applications
  • Support ongoing architecture evaluation and performance studies
  • Compare architectural concepts and help shape Quandela’s architecture roadmap
  • Lead exploratory research and recommend new directions for architecture development

Requirements

  • PhD in quantum information, quantum computing, physics, mathematics, computer science, or a closely related discipline
  • Deep expertise in at least one relevant area, including quantum complexity theory, quantum learning theory, quantum-system characterisation, performance analysis, or quantum algorithms
  • Experience relating theoretical or computational work to practical implementation, hardware, or experimental constraints
  • Ability to evaluate the capabilities and limitations of quantum systems or architectures
  • Background in scientific modelling, numerical simulation, and Python-based scientific computing
  • Independence in research and the ability to frame and organise open-ended problems
  • Collaborative communication style with the ability to explain ideas clearly across disciplines
  • Professional proficiency in English
  • Knowledge of quantum error correction and early fault-tolerant architectures
  • Experience designing hardware-aware algorithms or architectures
  • Familiarity with quantum benchmarking and performance metrics
  • Experience with noise modelling
  • Experience analysing resource requirements and computational cost
  • Experience working with experimental or hardware-focused quantum-computing teams
  • Familiarity with quantum compilation or native-gate-aware circuit design
  • Knowledge of photonic quantum computing
  • Experience with resource estimation
  • Experience comparing quantum methods with strong classical baselines
  • Previous ownership of collaborative research projects
  • Postdoctoral or equivalent industrial R&D experience is welcome, as are recent PhD graduates with a strong record of scientific independence

Benefits

  • Investigate open scientific questions informed by real hardware constraints
  • Collaborate across Quantum Information, Device Physics, FTQC, and Algorithms
  • Own broad, exploratory research initiatives
  • Help shape the scientific direction of a growing team
  • Competitive compensation based on experience and level of responsibility
  • Company savings plan
  • Full health coverage through Alan
  • Transport reimbursement or sustainable mobility bonus
  • Swile meal vouchers
  • Gymlib access
