Entanglement Generation in Clifford Quantum Cellular Automata — •Johannes Gütschow1, Zoltán Zimborás2, and Reinhard Werner11Institut für Mathematische Physik, TU Braunschweig, www.imaph.tu-bs.de — 2Theoretische Physik, Universität des Saarlands, www.uni-saarland.de/fak7/rieger

Clifford Quantum Cellular Automata (CQCA) are a special kind of Quantum Cellular Automata that incorporate Clifford group operations for the time evolution automorphism. Despite being classically simulable, they can be used as basic building blocks for universal quantum computation. This is due to the connection to translation-invariant stabilizer states and their entanglement properties. We investigate the generation of entanglement under CQCA action and show analytical and numerical results for the growth of entanglement for different classes of states and CQCA.
