Hybrid Computational Architectures: Bridging Digital Logic and Chemical Systems towards Scalable and Efficient Computing

The rapid progress of digital computing faces limits due to processing constraints and power losses. Chemical and molecular computing present an alternative, but their scalability is restricted by a lack of precise programmability. To overcome these challenges, we propose a hybrid computational architecture that integrates digital programmability with chemical processes. Our system utilises a digitally controlled chemical array based on the nonlinear Belousov-Zhabotinsky reaction, functioning as a probabilistic computational substrate. This approach improves efficiency by partitioning information in chemical and digital substrates with a feedback loop, incorporating error correction, and using nearest-neighbour coupling and hysteresis for computation. We demonstrate its potential through physical instantiation of one- and two-dimensional Cellular Automata, showcasing the emergence of dynamic, life-like structures. Furthermore, we show the application of hybrid computation as a potential solution for solving combinatorial optimisation problems, demonstrating the promise of chemical-digital hybrid architectures for scalable, efficient computing.
