About XanaduXanadu’s mission is to build quantum computers that are useful and available to people everywhere.At Xanadu, we are learners, innovators, researchers, collaborators and problem solvers. We are creating something that has never been built before. Few people in their life will be able to be a part of something like this, where if we are successful, the technologies we develop will solve some of the world’s most challenging problems, and literally change the world. And that is something to be excited about!Your role and responsibilitiesIn this role you will help develop the numerical toolkit for fault‑tolerant photonic quantum computing architectures. Improvements to the scalability and performance of the architectures can enter anywhere in the stack, requiring a broad understanding of Xanadu’s public architecture and its iterations, but the focus will be on the interface between the physical entangling and logical error‑correction layers. Although you can expect some analytical work at various levels of abstraction, from optical circuits to qubit quantum error correction, the focus will be on the development of our in‑house software tools. This will involve using, maintaining, optimizing, and introducing new features to the existing fault‑tolerant software stack to run large‑scale error‑correction simulations for the purpose of evaluating performance and estimating resources.Basic qualifications and experienceMSc. in Physics, Mathematics, Computer Science, or Engineering,
