Abstract

An implementation and review of our recently proposed scenarios [1-13] for processing and transfer of information is presented. We will show how computing using molecular potentials and vibronics communications can be adapted to upgrade present charge-current approaches, which are already in the limits of their technical and perhaps physical limits because their immense heat dissipation problems. It has long been recognized the many advantages and potential payoffs that the development of THz based applications could bring to the military and security areas. We focus our implementation in the development of THz sensing and imaging for a wide range of military and security applications as systems operating at these frequencies have shown to have high sensitivity and selectivity when applied to the analysis of molecules. These are properties that are highly desirable in the design of sensing tools for the detection, identification and characterization of chemical and biological agents; and in the design of monitoring tools for the detection of these substances, both in closed and, with less selectivity, in open environments. Many materials of interest for security applications including explosives, and chemical and biological agents have characteristic THz fingerprints which set them apart from non-hazardous materials, thus allowing their identification. As molecular electronics techniques become available [14], they could sharply improve our present detection and sensing techniques.
