| Research Abstract |
In this research, we have proposed a novel computational architecture exploiting noise-induced phenomena in the concept of harnessing noise in real world systems. In particular, we focused on two systems. One is the calculation system driven by fluctuations called Brownian circuits, which achieve computational universality. We have developed the theory of the Brownian circuits to work under deterministic noise, namely chaotic fluctuations, using chaotic synchronization. The other is a stochastic resonance theory for logical operations. We have applied this theory to higher dimensional systems such as a genetic network model and proposed a new method how to parallelize logic gates in such systems.
