We were one among the few groups that pioneered the field of quantum biology. We introduced the study of the fundamental quantum dynamics of the radical-pair mechanism. Radical-ion-pair reactions are spin-dependent biochemical reactions relevant to photosynthesis and the avian magnetic compass. The radical-pair mechanism, the cornerstone of the field of spin chemistry, was known since the 60’s. Our group was the first to unravel the rich quantum-information science behind this biological mechanism, showing that concepts like quantum measurements, the quantum Zeno effect, measures of quantum coherence and even the quantum-communications concept of quantum retrodiction are necessary to understand the underlying quantum dynamics of radical-pairs.
