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.\nLearn more at: Quandela | Leading Photonic Quantum Computing Solutions\nOur ambition is to build large-scale fault-tolerant quantum computers.\nWithin Scalable Architecture, we model the physical systems behind our technologies to understand their limitations and guide future designs.\nAbout this position:\nYou will join our Device Physics team, which develops theoretical and numerical models of Quandela’s physical systems in close interaction with experimental teams.\nYou will focus on quantum dots and their phononic environment, modelling how phonon-induced noise affects our semiconductor photon sources.\nYour work will range from calculating phonon spectral densities to integrating these effects into existing source models. The scientific problem and possible approaches are already identified, giving you a strong foundation from which to progressively take ownership of the topic.\n-\nWhat you'll do:\nAs a Quantum Information Scientist working on Quantum Dot Modelling, you will:\nDevelop numerical models of quantum dot-phonon interactions and phonon-induced noise. \nCalculate relevant physical quantities, including phonon spectral densities, and integrate them into existing source models. \nApply finite-element, finite-difference and related numerical methods to semiconductor nanostructures. \nBuild and run simulations using COMSOL Multiphysics or comparable simulation platforms. \nValidate your models against physical expectations, existing models and experimental results. \nDevelop scientific code primarily in Python, with opportunities to move toward C++ for more demanding simulations. \nUse validated models to explore possible improvements in photon-source design and operation. \n-\nHow you'll grow:\nDuring your first months: Become familiar with Quandela’s quantum-dot systems and develop your first phonon simulations with support from Device Physics and experimental teams.\nWithin 6-12 months: integrate and validate your work within our wider modelling framework and take increasing ownership of the topic.\nLonger term: Explore optimisation strategies, additional physical effects and new research directions around semiconductor quantum systems.\nRequirements\nWhat we're looking for:\nWe are looking for a scientist combining strong physical understanding with hands-on numerical modelling experience, ideally in semiconductor, condensed-matter or computational physics.\nDirect quantum-computing experience is not required. What matters is your ability to translate a physical problem into a credible numerical model and critically assess its results.\nMust-have:\nMaster’s or PhD in Physics, Photonics, Semiconductor Physics, Condensed Matter Physics, Computational Physics or a closely related field. \nStrong foundations in semiconductor, condensed-matter or related quantum physics. \nHands-on experience modelling physical systems numerically. \nExperience with FEM, finite-difference or related numerical methods, ideally using COMSOL Multiphysics or comparable simulation tools.\nPython for scientific modelling and data analysis. \nAbility to understand the physics behind a simulation, challenge its assumptions and validate its results.\nAbility to collaborate with both theoretical and experimental researchers. \nProfessional English. \nImportant, but you can grow here:\nQuantum-dot or semiconductor nanostructure modelling. \nPhonon physics and phonon-induced noise. \nExperience with multiphysics or electromagnetic simulation tools, including Ansys or Lumerical. \nC++ for scientific computing. \nScientific or quantum-modelling packages such as QuTip. \nBonus:\nPhonon engineering. \nModelling of charge, nuclear-spin or other semiconductor noise mechanisms. \nExperience connecting numerical models with experimental measurements. \nQuantum-information knowledge and an understanding of how physical noise impacts quantum computation. \nWe are open to strong Master’s-level profiles with substantial hands-on research experience in numerical modelling. You do not need expertise across every layer of the problem.\nBenefits\nJoin a research team where theoretical and numerical work directly feeds into experiments and hardware development.\nWork on a concrete scientific problem connected to Quandela’s semiconductor photon sources. \nCollaborate closely with theorists and experimental physicists.\nProgressively build scientific ownership as your models become part of Quandela’s wider modelling framework. \nContribute to publications, conferences and new research directions. \nPlus:\nCompetitive compensation aligned with your experience and level of responsibility. \nCompany savings plan. \n100% health coverage through Alan. \nTransport reimbursement or sustainable mobility bonus. \nSwile meal vouchers. \nAccess to Gymlib. \nProcess\nTalent Acquisition interview, 30-45 min \nScientific interview with members of the team \nDiscussion of your previous research and numerical-modelling experience \nTechnical scientific discussion \nReference checks\nFinal discussion with the team \nOffer \nThe scientific discussions are intended to understand how you approach a physical modelling problem, choose appropriate numerical methods, assess assumptions and connect simulation results with a real physical system.\nBeyond that:\n If you enjoy using numerical modelling to understand real physical systems and seeing that work feed into experiments, this role offers the opportunity to deepen your expertise in semiconductor quantum systems while progressively taking ownership of the topic.","description_format":"text","description_chars":6269,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Quantum
