Developing Photodynamic Drugs

Photosensitizers have complex excited-state dynamics involving multiple spin states and singlet-triplet transitions, which are difficult to model accurately. Also, the behaviour under light is hard to simulate, making the drug development process extremely difficult.

Quantum computing offers a powerful way to simulate the electronic structure and photoactivation pathways of photosensitizers with greater accuracy and efficiency, capturing quantum effects that classical models struggle with.

This unlocks the ability to design and screen novel photodynamic drugs more effectively, accelerating discovery and enabling new treatments for cancer and infections that were previously too complex to develop.
