TLDR
A significant feature of this scheme is that a single nonlinear drive-response circuit can be used to flexibly yield the different logic gates, and switch logic behavior by small changes in the parameter of the response system.Abstract:
We introduce a scheme to obtain key logic-gate structures, using synchronization of nonlinear systems. We demonstrate the idea explicitly by numerics and experiments on nonlinear circuits. A significant feature of this scheme is that a single nonlinear drive-response circuit can be used to flexibly yield the different logic gates, and switch logic behavior by small changes in the parameter of the response system; so the response system can act as a ``logic output controller.'' Thus this scheme may help to construct dynamic general-purpose computational hardware with reconfigurable abilities.read more

Chaogates: morphing logic gates that exploit dynamical patterns.
TL;DR: The basic concepts underlying chaotic systems are reviewed and an extension of the formalism to include asymmetric logic functions is presented, which forms the basis of the design of a dynamical computing device that can be rapidly morphed to become any desired logic gate.

Vibrational resonance and implementation of dynamic logic gate in a piecewise-linear Murali–Lakshmanan–Chua circuit

TL;DR: It is shown that an optimal amplitude of the high frequency second harmonic driving enhances the response of a piece-wise linear non-autonomous Murali–Lakshmanan–Chua (MLC) system to a low frequency first harmonic signal.

Logic from nonlinear dynamical evolution
TL;DR: This work proposes a direct and flexible implementation of logic operations using the dynamical evolution of a nonlinear system, and demonstrates how the single dynamical system can do more complex operations such as bit-by-bit addition in just a few iterations.

Time shifts and correlations in synchronized chaos.
TL;DR: In this paper, a transfer function from the coupling model that provides estimates of the correlation between the drive and response waveforms, and of the time shift (i.e., lag or anticipation) of the synchronized state is introduced.

TL;DR: High-speed long-distance communication based on chaos synchronization over a commercial fibre-optic channel is demonstrated, showing that information can be transmitted at high bit rates using deterministic chaos in a manner that is robust to perturbations and channel disturbances unavoidable under real-world conditions.

Communication with Chaotic Lasers
TL;DR: The experimental demonstration of chaotic communication with an optical system is described, using an erbium-doped fiber ring laser to produce chaotic light and embedded in the larger chaotic carrier and transmitted to a receiver system where the message was recovered from the chaos.

Communicating with chaos.
TL;DR: It is shown that the recent realization that chaos can be controlled with small perturbations can be utilized to cause the symbolic dynamics of a chaotic system to track a prescribed symbol sequence, thus allowing us to encode any desired message in the wave form from a chaotic oscillator.
