Resource reduction via repeaters in entanglement distribution
arXiv:quant-ph/0103023 · doi:10.1103/PhysRevA.65.022321
Abstract
We show that the amount of entanglement needed as an initial resource to set up a certain final amount of entanglement between two ends of a noisy channel can be reduced in certain cases by using quantum repeaters. Our investigation (for various channels) considers cases when a large number of entangled pairs are transmitted through the channel using known asymptotic results and conjectured bounds on distillable entanglement.
