  This paper introduces a category theory-based framework to redefine physical
computing in light of advancements in quantum computing and non-standard
computing systems. By integrating classical definitions within this broader
perspective, the paper rigorously recontextualizes what constitutes physical
computing devices and processes. It demonstrates how the compositional nature
and relational structures of physical computing systems can be coherently
formalized using category theory. This approach not only encapsulates recent
formalisms in physical computing but also offers a structured method to explore
the dynamic interactions within these systems.
