Selecting the best factory is a highly multi-parameter optimization problem, coupling spatial and temporal code distances, single- versus multi-output protocols, the degree of parallelism of the distillation circuit, the magic state injection scheme, the factory layout, and hardware connectivity constraints.\nThe Quantum Compilation Intern helps navigate this design space to identify the most resource-efficient factories for Alice & Bob’s\narchitecture, focusing first on magic state factories and possibly extending the resulting tools to Clifford state factories.\nReporting to the Quantum Compilation PhD Researcher (CIFRE), with possible co-supervision by Élie Gouzien, they will work closely with the Compilation and QEC teams to design, compile and optimise distillation factories for Alice & Bob’s architecture, and may design new distillation protocols along the way. This work feeds directly into Alice & Bob’s physical resource estimates for (early) fault-tolerant quantum computation.\nThe internship starts between January and March 2027 !\nResponsibilities:\n Review the state of the art in magic state distillationSurvey single- and multi-output (batched) protocols, qubit-recycling techniques and unfolded\n(physical-level) distillation\nIdentify promising candidates for Alice & Bob’s architecture, including two-stage strategies\ncombining physical- and logical-level distillation\n\nCompile distillation protocols to Alice & Bob’s logical instruction setTranslate selected protocols into sequences of logical operations native to Alice & Bob’s\narchitecture\nIntegrate magic state injection schemes and hardware connectivity constraints into the\ncompiled protocols\n\nDesign and optimise factory layoutsPropose concrete layouts for repetition-code and LDPC-code architectures\nMinimise factory space-time volume by jointly optimising code distances, degree of paral-lelism and placement of operations\nDevelop resource-estimation and noise-simulation tools\nBuild a tool exploring the multi-parameter design space and computing the space-time cost\nof candidate factories\nRun circuit-level noise simulations to validate factory output fidelities and refine the resource\nestimates\n\nExtend the scope and communicate resultsDesign new distillation protocols where the exploration reveals gaps, and apply the developed\ntools to Clifford state factories\nDocument results in an internal report and, where relevant, contribute to publications or\ninvention disclosures\n\nRequirements:\nYou are curious and rigorous, comfortable with open-ended research questions, and able to work independently while engaging regularly with the team.\n Education: Master’s degree (M2) in progress in physics, computer science or quantumengineering\n\nLanguages: Proficient in English\n Experience No prior professional experience required;
