Quantum Cloning by Cellular Automata
arXiv:1212.4704 · doi:10.1103/PhysRevA.87.032337
Abstract
We introduce a quantum cellular automaton that achieves approximate phase-covariant cloning of qubits. The automaton is optimized for 1-to-2N economical cloning. The use of the automaton for cloning allows us to exploit different foliations for improving the performance with given resources.
