摘要：

In this paper, we present the explicit transformations of the optimal 1 -> 3, 4,5 phase-covariant cloning in 3 dimensions. The cloning fidelities are covered by the theoretical bounds of the optimal 1 -> 3k, 3k + 1, 3k + 2 phase-covariant cloning of qutrits, where k >= 1 is the integral [Phys. Rev. A 67 (2003) 042306].
