Abstract

Radical-ion-pair reactions, central for understanding the avian magnetic compass and spin transport in photosynthetic reaction centers, were recently shown to be a fruitful paradigm of the new synthesis of quantum information science with biological processes. We here show that the master equation so far constituting the theoretical foundation of spin chemistry violates fundamental bounds for the entropy of quantum systems. In contrast, a new theory based on quantum measurements, quantum coherence measures and quantum retrodiction, thus exemplifying the paradigm of quantum biology, satisfies the same bounds. By considering the quantum information extracted during the reaction we also unravel new magnetic- field effects not conveyed by reaction yields. The results of the thesis are uploaded in arXiv : 1607.03071
