This Defense Intelligence Reference Document, dated 10 December 2010, was prepared by the Defense Intelligence Agency's Defense Warning Office under the Advanced Aerospace Weapon System Applications program. It examines quantum computing and DNA-based molecular computing as options for onboard supercomputing in future spaceflight. It forecasts working ion trap quantum computers within 10 years, simple DNA tile computing within 20 years, and self-repairing DNA computers and hybrid quantum dot systems on a 40-year horizon.
From the source:Release of 2026-09-18 Incident: 12/10/10, Las Vegas, Nevada. Released with redactions. This document is a Defense Intelligence Reference Document (DIRD), a technical reference format used by the Defense Intelligence Agency (DIA) to capture baseline knowledge on a specific topic for later analytic use. DIRDs are best understood as reference and synthesis products rather than as original research. It is one of 38 DIRDs produced under the Advanced Aerospace Weapon System Applications Program (AAWSAP) between 2009 and 2011. Because AAWSAP’s scope permitted a broad range of supporting topics, not every DIRD in the series directly concerns aerospace systems or future threat assessment. The following summary reflects the DIRD’s scope and framing at the time of writing and should not be read as implying current validation of the concepts discussed. This DIRD surveys advanced computing concepts for future space and automation applications, focusing on quantum and molecular (DNA-based) computing as potential alternatives to conventional silicon electronics. The report introduces quantum computing principles alongside DNA-based logic gates, self-assembly, and nanoscale repair mechanisms, arguing that these unconventional architectures might eventually offer advantages in radiation tolerance, physical robustness, and specialized onboard processing for space-based platforms. It notes that near-term practical barriers remain substantial. Quantum systems continue to depend on complex cryogenics, shielding, and unsolved reliability challenges, while DNA-based computing remains a far-future concept rather than a viable alternative to general-purpose processors. Overall, the document presents both frameworks as long-term possibilities to complement, rather than immediately replace proven space-qualified electronics. It concludes that the stronger, nearer-term cases for such architectures are in highly specialized or hybrid roles rather than in fully mature general-purpose onboard computing applications.
UNCLASSIFIED/ /FOR OSSICIAl WSE 8Ht'I" constant concentration around the crystal can easily be realized by a constant flow. This ground-breaking work in DNA synthesis technology has opened the door for several applications in genetic engineering and lab on a chip technology (107)(108)(109). This kind of controlled self-assembly will drastically improve the size and yield of errorless nano structure. It is also possible to produce desired nano structures on a patterned template in the reaction chamber for various applications . Glass plate 011 Figure 16. Micro-fluidic device for DNA tile self-assembly . DNA Origami The idea of holding helical domains in a parallel arrangement via the juxtaposition of antiparallel crossovers has become a general principle in DNA nanotechnology, used in at least a dozen constructions . For example, it has been extended to molecules with three parallel helixes (110) and it has been used to attach triangles rigidly to a nanomechanical device. (111) However, these techniques do not create a generalized multi-crossover molecule with parallel helices due to the inability to have the ratio of the component short strands exactly equal. Single-stranded origam i such as William Shih's octahedron (113) cannot, by definition, suffer from this problem. Scaffolded origami sidesteps the problem of equalizing strand ratios by allowing an excess of helpers to be used. As long as each scaffold strand gets one of each helper, all scaffolds may fold correctly (some might get trapped in misfolding). Because origami are easily differentiable from the helpers, separating them is not difficult (e.g. large origami stick much more strongly to mica surfaces than do tiny helpers and so excess helpers can be washed away). Single-stranded origami and scaffolded origami thus seem the best candidates for the creation of large complex structures. As Shih has observed, the geometry used for the octahedron should generalize and allow the creation of arbitrary polygonal networks. Generalization of the parallel helical geometry introduced by double crossover molecules is simple using scaffolded DNA origami; Ruthemond has recently demonstrated the technique for the creation of six arbitrary shapes and six arbitrary patterns (including the one shown here); the design method and experiments showing its generality are described in (114). To get a feeling for the method, look at Figure 18. Shapes are approximated by laying down a series of parallel helical domains inside of the shape (Figure 18a). Helices are cut to fit the shape, in a series of sequential pairs from top to bottom, so UNCLASSIFIED// FOR OPPICIJ!tt tJ!JE 8Hllf 32
