Temporal witnesses of non-classicality in a macroscopic biological system

Scientific Reports Nature Research 14:1 (2024) 20094

Authors:

Giuseppe Di Pietra, Vlatko Vedral, Chiara Marletto

Abstract:

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 then propose a general qubit model for the quantum transfer of an exciton along a bio-polymer chain, also discussing the effects of environmental decoherence. The generality of our results makes them ideal candidates to design new tests of quantum features in complex bio-molecules.
