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 responsibilities:

As a theoretical quantum optics researcher, you will work with us towards building photonic quantum computers. You will collaborate with the world-class researchers at Xanadu (including 40+ PhDs) to help devise and develop architectures for fault-tolerant photonic quantum computing by

  • Deeply understand and model the quantum optical properties of photonic hardware, which includes squeezed states, linear optics, homodyne detection and photon-number resolving detection.
  • Devise scalable methods to characterize quantum optics hardware and work with the hardware team to implement these.
  • Analyse the effect of the quantum optical properties on the performance of the quantum computation.
  • Inform the development of hardware.
  • Write patent applications and peer-reviewed articles reporting advances where applicable.

Required Qualifications and Experience:

  • PhD degree in Physics, Mathematics, Computer Science or a related technical field.
  • Expertise in theoretical quantum optics or integrated quantum photonics.
  • Demonstrated combination of strong problem solving skills, high creativity and attention to detail.
  • Demonstrated interest and commitment toward understanding and collaborating with experimental, simulation and theory teams.
  • Demonstrated strong communication skills, especially in interdisciplinary teams.
  • Ability to operate in a fast-paced environment and manage multiple competing priorities.

Preferred Knowledge and Experience:

  • Postdoctoral research experience in quantum optics.
  • Demonstrated ability at learning new research topics.
  • Familiarity with non-linear optics, continuous variable quantum information and quantum error correction.
  • Proficiency in working with Python or other modern programming languages.


To build quantum computers that are useful and available to people everywhere.
