Abstract

A quantum model of excitation transfer from a donor molecule to an acceptor molecule through a biomolecule represented by a quasi-one-dimensional molecular chain is proposed. The sites of the chain correspond to the structural elements of biomolecules, such as amino acid residues linked into the chain by peptide bonds in proteins or nucleotides in RNA and DNA. Particular attention is paid to the emergence of quantum entanglement between the donor and acceptor molecules as the specific type of quantum correlations, which provides an intramolecular quantum channel for information transmission.
