We demonstrate that local transformations on a composite quantum system can be enhanced in the presence uf certain entangled states. These extra states act much like catalysts in a chemical reaction: they allow otherwise impossible local transformations to be realized, without being consumed in any way. In particular, we show that this effect can considerably improve thr efficiency of entanglement concentration procedures for finite states.
