# A Gentle Introduction to Lattice Field Theory

## TL;DR

This paper introduces Lattice Field Theory to non-experts, explaining its principles and successes, and connects it to Quantum Cellular Automata.

## Contribution

It provides a clear, accessible overview of Lattice Field Theory and its relationship with Quantum Cellular Automata.

## Key findings

- Lattice Field Theory has achieved notable successes in modeling physical systems.
- There is a conceptual link between Lattice Field Theory and Quantum Cellular Automata.

## Abstract

The principles of Lattice Field Theory (LFT), in particular Lattice Gauge Theory (LGT), are explained for a nonspecialist audience. We describe some of the successes of the program; we also discuss the relationship between LFT and Quantum Cellular Automata (QCA).
