Quantum Information Scientist - Architecture & Performance H/F Quandela

Join a growing quantum-computing company and contribute directly to the research behind future generations of quantum architectures.

• Explore open scientific questions grounded in real hardware constraints.
• Work across Quantum Information, Device Physics, FTQC and Algorithms.
• Take ownership of broad and exploratory research projects.
• Contribute to the scientific directions of a growing team.

Plus:

• Competitive compensation aligned with your experience and level of responsibility.
• Company savings plan.
• 100% health coverage through Alan.
• Transport reimbursement or sustainable mobility bonus.
• Swile meal vouchers.
• Access to Gymlib.

Process

• Talent Acquisition interview, 30-45 min
• Interview with Quantum Information hiring manager, 30-45 min
• Presentation of previous research workand discussion with members of the theory team
• Reference checks
• Technical discussion based on a scientific paper or research topic
• Offer
  

For the technical exercise, you may be asked to explore scientific material outside your direct area of expertise and discuss how you would connect it to a broader architecture problem.

What you'll do:

As a Quantum Information Scientist working on Architecture & Performance, you will:

• Evaluate and compare the capabilities and limitations of near- and mid-term quantum architectures.
• Draw on methods from complexity theory, benchmarking, characterisation and related fields to assess different architecture designs.
• Incorporate realistic noise, native operations and physical constraints into your analyses.
• Investigate when and how different architectures could provide meaningful computational capabilities or advantages.
• Develop scientific models and numerical tools to explore architecture-performance trade-offs.
• Study how architecture choices interact with algorithms, resource requirements and QEC strategies.
• Progressively propose and lead new research projects around architecture design and performance.

You will work across our Architecture team and Algorithms and Applications team, connecting questions from the physical layer to computational capability and potential applications.
