Suboptimal asymmetric economical phase-covariant quantum cloning and telecloning in d-dimension

We present the explicit transformation of the suboptimal asymmetric economical 1 → 2 phase-covariant quantum cloning in d-dimension without ancilla. We also present its telecloning protocol, which differs from the general ones in which the symmetry of the transformations are required.
