About the role
About Quandela: Quandela is a global leader in quantum computing, designing, building, and delivering cutting-edge quantum solutions for research and industry. Its offerings include the most energy-efficient quantum computers for data centers, full-stack quantum computing solutions accessible via the cloud, and algorithm access services for academic and industrial customers. Following a pragmatic, step-by-step roadmap, Quandela has been deploying industrial-grade systems since 2023 while developing future generations of fault-tolerant quantum computers capable of scaling through the integration of thousands of photonic components. Quandela is committed to making quantum computing accessible to all in order to address the most complex industrial and societal challenges. Learn more at: Quandela | Leading Photonic Quantum Computing Solutions Our ambition is to build large-scale fault-tolerant quantum computers capable of solving problems beyond the reach of classical computation. Getting there will require several generations of intermediate architectures. Choosing the right ones means understanding what can be built, what these systems can compute and how efficiently they can do so. About this position: You will join Quandela’s Quantum Information team within Architecture , working on the evaluation and design of our near- and mid-term quantum architectures. Your role will sit between quantum theory, computational capability and real hardware constraints . You will develop methods to evaluate architecture concepts, understand their performance and limitations, and help guide future architecture choices. Depending on your background, you may draw on complexity theory, quantum learning theory, quantum-system characterisation, benchmarking or related areas . You will work closely with our Device Physics, FTQC and Q.Algorithms Team. Requirements 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. - How you'll grow: During your first 3–6 months Become familiar with Quandela’s technologies, architecture roadmap and ongoing research while contributing to existing evaluation and performance studies. Within 1 year Take increasing ownership of architecture studies, compare different concepts and bring your own scientific perspective to the team. Longer term Lead exploratory research projects, propose new architecture directions and contribute to shaping Quandela’s future architecture roadmap. -- What we're looking for: We are looking for a scientist with a strong theoretical background in quantum computing, scientific autonomy and an interest in connecting different layers of the quantum-computing stack. Must-have • PhD in Quantum Information, Quantum Computing, Physics, Mathematics, Computer Science or a closely related field. • Strong expertise in one or more relevant areas, s
