Quantum conditional cloning of continuous variable entangled states
We extend the technique of conditional preparation to a quantum cloning machine, and present a protocol of 1 → 2 conditional cloning of squeezed state and entanglement states. It is shown that the entanglement degree of the cloned entangled states can be well preserved even when the fidelity between...
