Job description
About Xanadu:
Xanadu’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. What we are doing is extremely hard, the classic moon shot. 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 responsibilities:
In this role you will help improve the design of Xanadu photonic quantum computer by prototyping, co-designing, optimizing, and benchmarking its logical architecture. Improvements to the scalability and performance of the architecture can enter anywhere in the stack, requiring a broad understanding of logical compilation and computational units, gates, codes, decoders, magic state preparation approaches, and measurement-based quantum computing. You can expect a combination of analytical and numerical work at various levels of abstraction, from continuous-variable optical circuits to discrete-variable qubit quantum error correction. As a senior scientist you will also be involved in higher-level vision setting and design, as well as the management of people and projects.

Basic qualifications and experience:
  • PhD in Physics, Engineering, Computer Science or a related technical field.
  • Expertise in quantum computation theory, including quantum error correction under various noise models, codes, and decoders
  • Familiarity with the optical platform for quantum computation, especially bosonic codes such as GKP states and the continuous-variable formalism
  • Demonstrated Python programming skills e.g. for research, coursework, or personal projects (include GitHub profile on CV if available).
  • Demonstrated strong communication skills, e.g. papers, posters, conference talks, teaching experience.
  • Ability to operate in a fast-paced environment and manage multiple competing priorities/deadlines.

Preferred qualifications and experience:
  • PhD, postdoctoral or industry experience in quantum physics or technology
  • Deep understanding of quantum optics and/or MBQC.
  • Knowledge of software development best practices
  • Experience with high-performance computing

This is for a new position. Your base salary will be determined based on your location, experience, and internal benchmarks. The base salary range is 140,000 - 190,000 CAD. You will also be eligible for equity and benefits.
