Bounds on QCA Lattice Spacing from Data on Lorentz Violation
Leonard Mlodinow, Todd A. Brun
Recent work has demonstrated that discrete quantum walks, when extended to quantum cellular automata (QCA), can, in the continuum limit, reproduce relativistic wave equations and q…

Quantum Electrodynamics from Quantum Cellular Automata, and the Tension Between Symmetry, Locality and Positive Energy
Todd A. Brun, Leonard Mlodinow
We show that free QED is equivalent to the continuous-space-and-time limit of Fermi and Bose lattice quantum cellular automata theories derived from quantum random walks satisfying…
