摘要：

Cellular automata have recently been proposed as an architecture for dense, locally-interacting arrays of submicron devices. However, because conventional von Neumann cellular automata do not correctly reflect the long-range behavior of typical inter-device interactions, they do not provide a suitable theoretical model for the proposed device arrays. In this paper we define replica cellular automata, a class of cellular automata that can be generated from lattice-gas cellular automata. We show that for inter-device interactions that have a well-defined screening length D, replica cellular automata provide a suitable formal model. As an example of their applicability, we exhibit a computation-universal cellular automata architecture in which the cells consist of charge-transfer quantum dot devices.
