Integrated Multi-Physics Computational Substrates

The physical scaling and energy efficiency limits inherent to traditional Complementary Metal-Oxide-Semiconductor (CMOS) electronics have necessitated a fundamental architectural shift in global computational infrastructure. The core constraint—the power dissipation density of interconnects—is reaching thermodynamic barriers, making further purely electronic scaling economically unsustainable for petascale data processing requirements. Integrated Multi-Physics Computational Substrates represent the mandatory convergence of three distinct physics domains onto a single functional chip: electrical signaling (CMOS), integrated photonics (optical transmission), and ambient field/quantum interactions (e.g., plasmonic or superconducting elements). This integration moves computation from being an exclusively electron-based process to a multi-physics system where data transfer, not merely logic gate operation, constitutes the primary architectural utility layer.
