▎ 摘  要

This paper presents a theoretical study of the implementation of an architecture of a quantum cellular automaton on a graphene nanoribbon. The cells of the automaton are made up by C-13 atoms and hydrogen atoms and the interaction between neighboring cells corresponds to the indirect coupling between nuclear spins. We have determined the relevant parameters characterizing the physical system for nuclear magnetic resonance and from knowledge of these parameters we have designed control protocols to study the evolution of the information through the quantum cellular automaton. Our results show that a graphene nanoribbon enriched with atoms of C-13 stores and processes quantum information in times less than the corresponding system decoherence times.
