    "abstract": "Quantum cloning machines for equatorial qubits are studied. For the case of 1\nto 2 phase-covariant quantum cloning machine, we present the networks\nconsisting of quantum gates to realize the quantum cloning transformations. The\ncopied equatorial qubits are shown to be separable by using Peres-Horodecki\ncriterion. The optimal 1 to M phase-covariant quantum cloning transformations\nare given.",
