A quantum network for implementation of the optimal quantum cloning
Dai Jie-lin, Wen‐Hai Zhang · Chinese Physics B · 2009
This paper presents a quantum network to implement the optimal 1 → 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.
