Chaotic attractor hopping yields logic operations
內容簡介：Certain nonlinear systems can switch between dynamical attractors
occupying different regions of phase space, under variation of parameters or initial
states. In this work we exploit this feature to obtain reliable logic operations. With
logic output 0/1 mapped to dynamical attractors bounded in distinct regions of phase
space, and logic inputs encoded by a very small bias parameter, we explicitly demonstrate that the system hops consistently in response to an external input stream,
operating effectively as a reliable logic gate. This system offers the advantage that
very low-amplitude inputs yield highly amplified outputs. Additionally, different
dynamical variables in the system yield complementary logic operations in parallel.
Further, we show that in certain parameter regions noise aids the reliability of logic
operations, and is actually necessary for obtaining consistent outputs. This leads us to
a generalization of the concept of Logical Stochastic Resonance to attractors more
complex than fixed point states, such as periodic or chaotic attractors. Lastly, the
results are verified in electronic circuit experiments, demonstrating the robustness of
the phenomena
