| Abstract: | This paper presents a quantum network to implement the optimal 1$
\to $2 quantum cloning in 2 dimensions, including the optimal
asymmetric universal, the optimal symmetric phase-covariant, and the
asymmetric real state cloning. By only choosing different angles of
the single-qubit rotations, the quantum network can implement three
optimal quantum cloning. |
