Abstract

In this paper, we show how a computing architecture, called "Salt", might be able to implement the workings of a particular Discrete Space-Time-State model of Physics (DSTSP). While what is presented is certainly not a correct model of fundamental processes in physics, it illustrates how such models could give us insights into new methods of modeling some attributes of microscopic physical systems. The main novelty of the approach is an unusual definition of a discrete space-time where time itself is made more complex in order to allow for simple representations of quantities that have properties in common with QM spin, charge and fractional charge, QCD color and reversibility with CPT symmetry.
