| Abstract: | We strictly prove the optimality of the asymmetric economical phase-covariant quantum cloning in dimensions working without ancilla. In proof, we derive another independent unitary transformation of this cloner. Our result covers previous contributions [Durt T, et, al, Phys. Rev. A, 2004, 69: 062316]. |
