Quantum Computing Jobs

• London
• Hybrid
• Mid-level

Develops novel quantum algorithms in computational topology and geometry, characterising resource requirements and noise-robustness, then implementing and optimising them on Quantinuum's quantum hardware using error mitigation and error correction. Works across the full quantum computing stack with hardware, QEC and software teams, and with academic and industry partners on quantum topological data analysis use cases.
