Realization of a universal and phase-covariant quantum cloning machine in separate cavities
Bao‐Long Fang, Qing-Min Song, Ye Liu · Physical Review A · 2011
We present a scheme to realize a special quantum cloning machine in separate cavities. The quantum cloning machine can copy the quantum information from a photon pulse to two distant atoms. Choosing the different parameters, the method can perform optimal symmetric (asymmetric) universal quantum cloning and optimal symmetric (asymmetric) phase-covariant cloning.
