Job description

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 99.99% 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 Quantum Scientist, you will be at the forefront of our research efforts, working hands-on with our current hardware while helping to shape future generations of quantum processors. Your work will span designing, coding, debugging, and executing experiments, developing novel control schemes, and pushing the boundaries of system performance.

What you'll be responsible for:

• Prototype and characterise coherent control and cooling schemes for trapped-ion qubits using laser and microwave fields.
• Calibrate and benchmark quantum systems, focusing on achieving ultra-low gate errors and optimising performance across device modules.
• Validate emerging trap technologies, including integrated electronics and photonics for large-scale architectures.
• Analyse experimental data, debug complex hardware/software interactions, and ensure reliability of qubit operations.
• Present results internally and externally, representing Oxford Ionics at conferences and in collaborations.

You will need a PhD in physics or a related discipline, with a strong foundation in atomic or qubit-related physics. Prior postdoctoral or industry experience is valuable, but this role is open to candidates moving directly from a PhD. A solid background in quantum control, with hands-on experience in calibration, benchmarking, or coherent control of qubits, would be desirable.

You will need:

• Proven expertise in experimental AMO physics or quantum computing. Experience with trapped ions is preferred.
• Strong collaborative skills, with the ability to work independently and as part of a fast-moving team.
• Prior experience in one or more of the following: spectroscopy or simulation of multi-level systems, characterisation of control hardware, gate fidelity benchmarking or running quantum algorithms on hardware.
• Strong proficiency in programming and data analysis.
• A track record of scientific communication through publications, talks and conferences would be advantageous.

Oxford Ionics is leading the way in quantum technology, and we need skilled, innovative individuals like you. We offer a range of benefits, including opportunities to further your career with a world-class team, business stock options, generous annual leave, flexible working, medical, dental and vision insurance for you and your family, and much more. Join us and be part of the future of quantum computing.

Oxford Ionics is committed to equal opportunity for all.
