Xanadu’s mission is to build quantum computers that are practical and available to people everywhere. 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. In 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.

MSc. in Physics, Mathematics, Computer Science, or Engineering,



especially in topics relevant to quantum information theory Several years of research or industry experience in related fields Strong experience with object‑oriented programming in Python Experience with high‑performance computing, including writing and running optimized and parallelized code on supercomputers and computing clusters Experience with software engineering best practices: testing, continuous integration, version control, documentation, and code review Familiarity with quantum computation theory, including quantum error correction under various noise models, codes, and decoders Great communication skills, and the ability to clearly express complex technical concepts Up‑to‑date knowledge of the latest developments in quantum computing and error‑correction Some experience programming in low‑level languages (e.g., C, C++) PhD in Computer Science, Physics, Mathematics, or Engineering is an asset They are fundamental and lay the foundation for culture at Xanadu. At Xanadu, we are committed to building an inclusive, safe, and equitable culture and fostering an environment where our employees feel included, valued, and heard. ai.
