Local Cloning of Arbitrarily Entangled Multipartite States
arXiv:quant-ph/0504216 · doi:10.1103/PhysRevA.73.012343
Abstract
We examine the perfect cloning of non-local, orthogonal states with only local operations and classical communication. We provide a complete characterisation of the states that can be cloned under these restrictions, and their relation to distinguishability. We also consider the case of catalytic cloning, which we show provides no enhancement to the set of clonable states.
