Quantum cloning machines for equatorial qubits
arXiv:quant-ph/0101101 · doi:10.1103/PhysRevA.65.012304
Abstract
Quantum cloning machines for equatorial qubits are studied. For the case of 1 to 2 phase-covariant quantum cloning machine, we present the networks consisting of quantum gates to realize the quantum cloning transformations. The copied equatorial qubits are shown to be separable by using Peres-Horodecki criterion. The optimal 1 to M phase-covariant quantum cloning transformations are given.
