We introduce a quantum cellular automaton that achieves approximate phase-covariant cloning of qubits. The automaton is optimized for 1 → 2N economical cloning. The use of the automaton for cloning allows us to exploit different foliations for improving the performance with given resources.

Abstract
We introduce a quantum cellular automaton that achieves approximate phase-covariant cloning of qubits. The automaton is optimized for 1 → 2N economical cloning. The use of the automaton for cloning allows us to exploit different foliations for improving the performance with given resources.File in questo prodotto:
