摘要：
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. (C) 2007 Elsevier B.V. All rights reserved.
