    "abstract": "When prior partial information about a state to be cloned is available, it\ncan be cloned with a fidelity higher than that of universal quantum cloning. We\nexperimentally verify this intriguing relationship between the cloning fidelity\nand the prior information by reporting the first experimental optimal quantum\nstate-dependent cloning, using nuclear magnetic resonance techniques. Our\nexperiments may further have important implications into many quantum\ninformation processing protocols.",
