Job description

Advanced R&D Scientist - Quantum Algorithms - 920 at Quantinuum, UK London or Cambridge. A mid-level full time position in the Quantum Algorithms and Machine Learning team, listed under quantum applications.

We are seeking a Research Scientist to join our team in Cambridge or London, working on the development of quantum algorithms with a focus on computing topological and geometric invariants of data. This role offers the opportunity to contribute to cutting-edge research aimed at advancing the capabilities of quantum computers and exploring their potential advantages for real-world applications.

In this role, you will develop novel quantum algorithms in computational topology and geometry, characterize their resource requirements and noise-robustness properties, and explore potential applications of these algorithms for data analysis in the near-fault tolerant era. You will implement these algorithms on Quantinuum’s quantum hardware and optimize their performance under realistic hardware constraints, leveraging error mitigation and quantum error correction.

You will collaborate closely with researchers across the full quantum computing stack—including hardware, quantum error correction, and software teams—to translate theoretical advances into experiments on real quantum processors. You will also support collaborations with academic and industry partners to explore and develop promising use cases for quantum topological data analysis.

Researchers in this role are encouraged to publish their work in leading scientific journals and present their results at top international conferences.
