Research Scientist, Quantum Algorithms (Optimization)

We are seeking a Research Scientist to join our team in London, working on the development of quantum algorithms with a focus on solving optimization problems. 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 and computational paradigms, and rigorously benchmark their performance against state-of-the-art classical methods. You will implement these algorithms, or key algorithmic primitives, on Quantinuum’s quantum hardware and optimize their performance under realistic hardware constraints, leveraging techniques such as 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. The role also involves supporting collaborations with academic and industry partners to explore and develop promising use cases for quantum optimization algorithms.

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