Production of Entanglement Entropy by Decoherence in Biological Systems

Marco Merkli
Memorial University of Newfoundland St. John's

We present a theoretical analysis of the entanglement entropy of an open dimer, such as a photosynthetic biological system of two excited states of chlorophyll molecules interacting with a protein-solvent environment, modeled by a field of oscillators. We show that the entanglement entropy of the chlorophyll dimer is generated by its decoherence, caused by the environment interaction. Depending on the type of interaction, not all environment oscillators carry signficant entanglement entropy. We identify the frequency regions in the environment which contribute to the production of entanglement entropy. Our results are mathematically rigorous.
