Evolutionary route to computation in self-assembled nanoarrays

Abstract

Ordered nanoarrays, i.e. regular patterns of quantum structures at the nanometre scale, can now be synthesized in a range of systems. In this paper I study a form of array computation where the internal dynamics are driven by intrinsic cell-cell interactions and global optical pulses addressing entire structure indiscriminately. The array would need to be 'wired' to conventional technologies only at its boundary. Any self-assembled array would have a unique set of defects, therefore I employ an ab initio evolutionary process to subsume such flaws without any need to determine their location or nature. The approach succeeds for various forms of physical interaction within the array. © 2008 IEEE.
