Abstract:

The study of multipartite entanglement has recently become of increasing interest in quantum information theory. One of the main goals is to characterize quantitatively and qualitatively multipartite entanglement. While for two-particle states, one copy entanglement manipulation is known, for multiparticle entanglement there still remain open questions concerning both classification as well as optimal local manipulations. In this work we present a proposition that gives an upper bound on the maximal probability for conversion of multipartite pure entangled states using only local operations and classical communication. Then we apply this proposition to some examples and show that it is possible to find the optimal transformation for particular cases.
