I have had a paper published that demonstrates how DNA acts as a quantum logic processor. It is entitled “Model of Biological Quantum Logic in DNA”, and it can be accessed at http://www.mdpi.com/2075-1729/3/3/474

The paper shows how the DNA molecule can act as a quantum logic processor via the demonstrated properties of coherent electron conduction along the pi stacking interactions of the aromatic nucleotide bases and electron spin filtering by interaction of the helicity of the DNA molecule with the spin of coherently conducted electrons, and also by the theoretical property of a logically and thermodynamically reversible enantiomeric symmetry in the deoxyribose moiety that allows nucleotides to act as quantum gates that are coherently concatenated by the above mentioned pi stacking interactions.

A video of a presentation that I made on this topic at the Research Seminar of the University of Tennessee Graduate School of Medicine on March 19, 2013 further illustrates the concepts involved, and it can be accessed at https://www.youtube.com/watch?v=GgPOhhx6hcQ

I would appreciate any comments.
