Senior Scientist, Quantum Sensing (Modeling and Control)
q-ctrl· Sensing Research
About this role
About the team
Q-CTRL’s Quantum Sensing Research team performs basic and applied research in quantum sensing and quantum-enabled navigation. It is a highly dynamic team comprising approximately 30 specialists in theoretical and experimental atomic physics, cold-atom interferometry, navigation modeling, and modern Bayesian estimation and signal processing techniques.
The Quantum Sensing Research and Quantum Sensing R&D teams work closely together, translating novel quantum sensing research into a useful capability and product. We are focussed on pushing the boundary of what is possible in quantum sensing and ensuring our R&D has real-world impact.
About the role
This opportunity will focus on developing next-generation, small-form-factor quantum magnetometers that are both exquisitely sensitive and able to operate reliably in harsh fielded environments.
To do this, you will design novel quantum control schemes and software-layer controls for optically pumped atomic magnetometers. You will also implement advanced statistical filtering techniques allowing performance improvements in noisy operating environments.
The algorithms, signal processing, and data analytics developed by you and the rest of the team will inform the design, build, and operation of our quantum sensors. In all cases, a major focus is on real-world performance in real-world environments.
What you'll be doing:
- Develop quantum control algorithms to improve the sensitivity and robustness of optically pumped magnetometers.
- Use statistical techniques such as Kalman and particle filters to improve sensitivity and remove noise.
- Perform time series analysis and develop platform and environmental noise compensation techniques using state-of-the-art digital signal processing and machine learning methods.
- Write simulations of atomic systems to explain and guide experiments.
- Develop, document, and review high-quality software using Python.
- Collaborate with your colleagues in the Quantum Sensing Team, the Quantum Sensing Division, and the company more broadly.
- Share your insights into control-augmented quantum sensing with the broader Quantum Sensing Division, company, external stakeholders and customers through verbal presentations and written outlets (e.g. academic publications, technical reports, blog posts).
- Other duties within the Employee's skills and experience, or with reasonable training.
Ideally you'll have:
- A PhD (or equivalent industry experience) in Physics, Engineering or a closely related discipline
- Experience with high-precision magnetometery.
- Experience in the theory, numerical modelling, and/or optimisation of one or more of the following: atomic spin ensembles, quantum sensing in warm atomic vapours, pulse-level optimisation and quantum control techniques.
- Knowledge of statistical techniques such as Kalman and particle filtering, estimator theory.
- Experience in time and frequency digital signal processing, e.g. adaptive filtering, Kalman filtering, match filtering.
- Contributing to a software system architecture with multiple components developed by different teams, adhering to best-practice software development principles.
Bonus points if you have (but not a necessity):
- Expertise with Python programming language for scientific computing.
- Experience modelling real quantum experiments/hardware and working closely with both theoretical and experimental teams.
- Experience with version control e.g. Git with CI/CD pipelines.
- Demonstrated experience in improving experimental outcomes through novel signal processing or denoising algorithms.
