We present conditions which guarantee that a composition of marker cellular automata has the same neighbourhood as each of the individual components. We show that, under certain te...
This paper presents the Collapsed Bennett Layout, a general purpose floorplan for reversible quantum-dot cellular automata (QCA) circuits. In order to exploit the full density and...

Abstract. This paper deals with simulation and reversibility in the context of Cellular Automata (ca). We recall the de nitions of ca and of the Block (bca) and Partitioned (pca) s...
It is shown that the set of hybrid one-dimensional reversible cellular automata (CA) with the periodic boundary condition is a regular set. This has several important consequences...
A reversible automaton is a finite (possibly incomplete) automaton in which each letter induces a partial one-to-one map from the set of states into itself. We give four non-trivi...
