Quantum Scientist - UK-070

Quantum is now, and it's built here.

Oxford Ionics, now part of IonQ, is pioneering the next generation of quantum computing. Using our world-leading trapped-ion technology, we’re building the most powerful, accurate and reliable quantum systems to tackle problems that today’s supercomputers cannot solve.

Joining Oxford Ionics means becoming part of a global IonQ team that is transforming the future of quantum technology - faster, at scale, and with real world impact.

What to expect:

We are looking for Quantum Scientists to join our UK Science team at Oxford Ionics. Our Quantum Scientists work at the forefront of our research efforts to develop the next generation of quantum computers.

They are responsible for validating and optimising the performance of our computers, playing a critical role in ensuring we are able to meet our research and development goals and timelines. Our Scientists’ work spans a broad range of areas from designing, coding, debugging and executing experiments, to developing and validating novel control schemes. They are responsible for documenting and sharing their findings with the aim of pushing the boundaries of system performance.

What you’ll be responsible for:

As a Quantum Scientist, you will typically be responsible for a subset of the following responsibilities:

• Prototyping and characterising coherent control and cooling schemes for trapped-ion qubits using laser and microwave fields.
• Calibrating and benchmarking quantum systems, focusing on achieving the highest fidelities for quantum circuit primitives (e.g. ion transport or gate operations) and full circuits.
• Validating emerging trap technologies, including integrated electronics and photonics for large-scale architectures.
• Analysing experimental data, debug complex hardware/software interactions, and ensure reliability of qubit operations.

Requirements

To be successful in this role, 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 we are open to applicants moving directly from a PhD.

We’re looking for someone with a solid background in quantum control, and hands-on experience in calibration, benchmarking, or coherent control of qubits, would be desirable. We’re looking for motivated scientists who can contribute to the progress of this fast moving, highly technical team and help the organisation meet our research goals.

You’d be a great fit with:

• Proven expertise in experimental AMO physics or quantum computing. Experience with trapped ions is beneficial though not essential.
• Prior experience in one or more of the following: spectroscopy or coherent control of multi-level systems, characterisation of control hardware, gate fidelity benchmarking or running quantum circuits on hardware.
• Strong proficiency in programming and data analysis, experience of Python or Rust is desirable.
• Strong collaborative skills, with the ability to work independently and as part of a fast-moving team.
• A track record of scientific communication through publications, talks and conferences would be advantageous.

Benefits

Be part of a team that’s shaping the future of quantum. We offer more than just a role, you’ll join a world class community of scientists, engineers and innovators working to unlock the full potential of quantum computing.

We offer a range of benefits, including opportunities to further your career alongside industry leaders, a competitive salary with IonQ stock options, an annual performance bonus, generous annual leave, flexible hybrid working, private medical and dental insurance for you and your family, and much more.

Join us and be part of the future of quantum computing.

We’re proud to be an equal opportunity employer and welcome applicants from all backgrounds.
