• Contract

Theoretical PhD project exploring how terahertz photons can control quantum matter, from Landau polaritons in high magnetic fields to topological qubits. Combines quantum optics, condensed-matter theory and numerical modelling of driven open quantum systems, with close links to experimentally achievable THz cavities.

• London
• Entry level
• Internship

Registering interest for ad-hoc internship positions lasting 3-6 months, mostly focused on specific projects or client collaborations rather than a formal summer programme. Work areas span quantum software development, chemistry, machine learning, algorithms, cybersecurity/encryption and hardware, with candidates ideally holding or pursuing a Master's or PhD.

Quantum Computing

• 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.
