Simulating quantum chemistry is difficult for ordinary computers, so we have developed and implemented algorithms to simulate chemistry on quantum computers, including the most advanced analog quantum simulation of chemical dynamics.

Organic semiconductors promise clean solar energy and lightweight electronic devices, and we are unravelling how they work and how to improve them. We have shown that delocalisation of charges and excitons can dramatically improve mobilities, charge generation, and device performance.

We aim to understand how solar energy conversion can be improved by coherence, whether of excitons, photons, or vibrations. We have shown that quantum effects play a role in photosynthetic complexes and that coherence in light-matter interactions can be engineered to improve light-harvesting efficiencies.
