QPolyDeg – Quantum computing for simulating UV-induced polymer degradation

In the QPolyDeg project, the consortium partners are investigating the use of quantum algorithms to calculate polymer degradation in surface coatings. These coatings degrade particularly on exposed structures such as airplanes or bridges under increased exposure to ultraviolet (UV) radiation, leading to material wear and safety risks.

To suppress polymer degradation, the individual degradation processes must be investigated. This is complicated because quantum-mechanically entangled electron states play a significant role in polymer degradation, which is why classical computational methods often reach their limits. Quantum algorithms promise a significant acceleration of quantum chemical calculations, from which the aerospace, automotive and construction industries can all benefit greatly.

The project receives funding from the Federal Ministry of Research, Technology and Space (BMFTR).
