Entanglement monotones for W-type states. Chitambar, E., Cui, W., & Lo, H., K. Physical Review A - Atomic, Molecular, and Optical Physics, 85(6):1-10, 2012.
Paper doi abstract bibtex In this article, we extend recent results concerning random-pair Einstein-Podolsky-Rosen distillation and the operational gap between separable operations (SEPs) and local operations with classical communication (LOCC). In particular, we consider the problem of obtaining bipartite maximal entanglement from an N-qubit W-class state (i.e., that of the form √x 0|000+√x 1|100++√x n|00) when the target pairs are a priori unspecified. We show that when x 0=0, the optimal probabilities for SEPs can be computed using semidefinite programming. On the other hand, to bound the optimal probabilities achievable by LOCC, we introduce entanglement monotones defined on the N-qubit W class of states. The LOCC monotones we construct can be increased by SEPs, and in terms of transformation success probability, we are able to quantify a gap as large as 37% between the two classes. Additionally, we demonstrate transformations ρ -n→σ -n that are feasible by SEP for any n but impossible by LOCC. © 2012 American Physical Society.
