Recent progress in science and technology has led to the revival of an old question concerning the relevance, of quantum effects in biological systems. Indeed Pascual Jordan’s 1943 book, Die Physik und das Geheimnis des Lebens had already posed the question “Sind die Gesetze der Atomphysik und Quantenphysik f¨ur die Lebensvorg¨ange von wesentlicher Bedeutung?” (Are the laws of atomic and quantum physics of essential importance for life?) and coined the term Quanten-Biologie (quantum biology). At the time this question was essentially of a theoretical nature as the technology did not yet exist to pursue it in experiment. Indeed quantum biology has been benefiting considerably from the refinement in experimental tools which is beginning to provide direct access to the observation of quantum dynamics in biological systems.
