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].
