About the Role
We are hiring a postdoctoral researcher to work on experimental quantum error correction (QEC) on IonQ's trapped-ion systems. You will design, run, and analyse QEC and fault-tolerant experiments on IonQ Aria and IonQ Forte, with dedicated hardware access. These are among the cleanest, highest-connectivity qubits publicly available, and the scientific goal is to turn that physical quality into demonstrable logical quality. Their all-to-all connectivity also makes code families available that are difficult to run on grid architectures.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
This is a hands-on, fast-paced position with room to shape the direction. You will work on experiments end to end, from code choice and native-gate compilation through to decoding real hardware data and writing it up.
Main Responsibilities
- Design, run, and analyse QEC and error-detection experiments on Aria/Forte, including logical state preparation and small-scale fault-tolerant primitives.
- Build and tune decoders against the measured device noise rather than idealized models.
- Characterize the hardware in the ways that matter for QEC (Circuit-level error rates, SPAM, correlated and leakage errors).
- Optimize circuits at the native-gate level to minimize depth and two-qubit count.
- Publish and present results, and collaborate with the group's work on quantum architecture and compilation.
Essential Requirements
- The successful candidate will hold (or be close to completion) a PhD in Computer Science, Physics, Applied Maths, or a closely related discipline, or equivalent research or industry experience.
- This position can be filled by an appropriate candidate at a Research Assistant (post-doc) or Research Associate (pre-doc) level, depending on relevant qualifications and experience.
- An appointment at a research associate level is dependent on having a PhD (or equivalent experience). Where a PhD has yet to be awarded, an appointment will initially be made as a research assistant and amended to research associate when the PhD is awarded.
