  Nucleic acids theoretically possess a Szilard engine function that can
convert the energy associated with the Shannon entropy of molecules for which
they have coded recognition, into the useful work of geometric reconfiguration
of the nucleic acid molecule. This function is logically reversible because its
mechanism is literally and physically constructed out of the information
necessary to reduce the Shannon entropy of such molecules, which means that
this information exists on both sides of the theoretical engine, and because
information is retained in the geometric degrees of freedom of the nucleic acid
molecule, a quantum gate is formed through which multi-state nucleic acid
qubits can interact. Entangled biophotons emitted as a consequence of symmetry
breaking nucleic acid Szilard engine (NASE) function can be used to coordinate
relative positioning of different nucleic acid locations, both within and
between cells, thus providing the potential for quantum coherence of an entire
biological system. Theoretical implications of understanding biological systems
as such "quantum adaptive systems" include the potential for multi-agent based
quantum computing, and a better understanding of systemic pathologies such as
cancer, as being related to a loss of systemic quantum coherence.
