    "abstract": "We consider the transformation of multisystem entangled states by local\nquantum operations and classical communication. We show that, for any\nreversible transformation, the relative entropy of entanglement for two parties\nmust remain constant. This shows, for example, that it is not possible to\nconvert 2N three party GHZ states into 3N singlets, even in an asymptotic\nsense. Thus there is true three-party non-locality (i.e., not all three-party\nentanglement is equivalent to two-party entanglement). Our results also allow\nus to make {\\em quantitative} statements about concentrating multi-particle\nentanglement. Finally, we show that there is true n-party entanglement for all\nn.",
