The idea is to exploit the effect of noise on nonlinear systems in order to extract different desired responses from it. We demonstrate the principle explicitly by implementing the fundamental NOR and NAND gates. We also demonstrate that one can efficiently switch logic behaviour by simply varying noise levels. Thus this scheme may help to construct dynamic general purpose computational hardware, with reconfigurable abilities, using the interplay between nonlinearity and noise.
