Temporal witnesses of non-classicality in a macroscopic biological system
Temporal witnesses of non-classicality in a macroscopic biological system
Exciton transfer along a bio-polymer is essential for many biological processes, for instance, light harvesting in photosynthetic biosystems. Here we apply a new witness of non-classicality to this phenomenon, to conclude that, if an exciton can mediate the coherent quantum evolution of a photon, then the exciton is non-classical. We …
