Senior Quantum Scientist

We are pioneering advancements in quantum computing by utilising trapped ion technology and our proprietary laser-free quantum control methods. Our research and development efforts build on our fully integrated quantum processors that can be fabricated within standard silicon foundries. This unique approach allows us to leverage the highest-performing qubit technology while ensuring scalability and manufacturability using existing semiconductor fabrication technology. We approach quantum computing with a focus on minimising errors, striving to achieve ultra-low gate errors at scale. Our immediate objective is to develop functional quantum computers within the NISQ regime, aiming to construct fault-tolerant machines that require minimal QEC overhead. Our recent breakthroughs include achieving 99.97% fidelity in two-qubit gates and 99.9992% fidelity in single-qubit operations without error correction, setting new industry standards for performance.

What to expect:

As a Senior Quantum Scientist, you will be at the forefront of our research and development, taking a leading role in both experimental design and the architecture of future generations of hardware. You will be responsible for driving innovation in coherent control, calibration, and benchmarking at scale, with a particular focus on enabling ultra-low error rates and system reliability across larger trapped-ion devices. Beyond hands-on experiments, you will help shape technical direction, mentor junior scientists, and ensure our work translates into scalable, fault-tolerant systems.

What you’ll be responsible for: 

• Leading the prototyping and characterisation of advanced coherent control schemes for trapped-ion qubits using laser and microwave fields.
• Driving system-level benchmarking and optimisation, ensuring near-term devices achieve world-leading performance and stability.
• Validating and integrating new trap technologies (e.g. on-chip electronics or photonics) to support scaling towards error-corrected architectures.
• Guiding junior scientists in experimental design, analysis, and presentation of results, while representing Oxford Ionics at external collaborations and conferences.

You will need a PhD in physics or a closely related discipline, with a strong foundation in atomic or qubit-related physics and typically four or more years of post PhD experience in quantum control, either in academia or industry. Alongside deep technical expertise, you should be able to work independently, lead projects, and collaborate effectively within a small, fast-paced team.

You will need:

• Proven expertise in experimental ion-trapping physics, ideally with a focus on quantum information processing and strong programming skills.
• Hands-on experience in spectroscopy, calibration, benchmarking of qubit systems, and debugging complex experimental setups.
• Strong proficiency with control software, hardware integration and data analysis.
• A track record of effective collaboration across teams and clear communication of complex scientific results through publications, talks, or conferences.
