I am interested in utilizing the tools commonly used in nonlinear dynamics, chaos theory and information theory to create novel chaos based systems. Chaotic systems are inherently sensitive to the change of both initial conditions and system parameters. This fundamental instability is typically viewed as an engineering challenge, requiring control mechanisms to tame the dynamics and give predictable outcomes. However, if handled carefully, chaotic dynamics can also be exploited to produce novel and counter-intuitive applications. A recent celebrated example is a chaogate, a logic gate that uses patterns generated by chaotic dynamics to transform input bits to the desired outputs. One of the unique and powerful capabilities of chaogates is that they can be reconfigured within a single clock cycle into any other logic gate. Thus, chaogates provide hardware-level programmability of circuit elements. Since the enhanced levels of security are embedded in the physical behavior of the system, chaogates are promising candidates for a new era of secure computing, and thus have a potential for a broad impact on society’s use of networked computing.

In principle, chaos-based logic gates can be implemented within any physical system exhibiting a sufficient level of chaos. Numerous “exotic” implementations have been proposed, but thus far realizations have been restricted to macroscopic nonlinear circuit elements. I am currently working on developing necessary theoretical foundation whose final goal is to use Rydberg atoms as a chaos-based computer.
