Abstract

Using nucleotide architectures to very closely and precisely place chromophores on a nucleic acid template to form dye aggregates that produce quantum coherent excitons, biexcitons, and triexcitons upon excitement to create excitonic quantum wires, switching, and gates that would then form the basis of quantum computation. Creating the various excitons and controlling the timing of the excitons would be performed using light of the corresponding wavelength and polarization to stimulate the corresponding chromophores.
