Defense Intelligence Agency · 54 pages · text from the file's own layer

This Defense Intelligence Reference Document from the Defense Intelligence Agency, dated 10 December 2010, is one of a series of advanced technology reports produced in FY 2010 under the Advanced Aerospace Weapon System Applications (AAWSA) Program. It reviews quantum computing technologies and DNA-based molecular computing for onboard supercomputing on future spacecraft. It forecasts ion-trap quantum computers within 10 years, simple DNA tile computing within 20 years, and self-repairing DNA computers on a 40-year horizon.

Deoxyribozyme-based Boolean Automata
The deoxyribozyme logic gates were applied to the construction of the first DNA-based
Boolean automata capable of autonomously responding to human inputs: "MAYAs" are
automata playing a game of tic-tac-toe against a human player. In tic-tac-toe there are a
maximum of 4 moves by the human player when MAYA has the first move. The initial MAYA
automaton played a simplified game, always claiming the center first, and the first human
move is symmetry-restricted to one corner or one side move. These simplifications led to a
representation of the game as a series of Boolean formulae that compute the automaton's
output in each well, based on the human inputs present in all wells. These formulae were
mapped to 23 deoxyribozyme-based logic gates by arranging gates in the individual wells
around a common substrate. These "hard-wired" automata give the human no chance to win
(Figure 22, Figure 23). (120, 122) One, two and three input deoxyribozyme-based logic
gates are allosterically modulated by 32 human-operated input oligonucleotides: 97 logic
gates distributed across 9 wells which calculate automaton moves, and 32 gates (boxed)
display human moves by implementation of a two-color fluorogenic output system. Even
though this mechanism is simplistic in nature, it has performed flawless Boolean calculations.
