General Theory of Environment-Assisted Entanglement Distillation
General Theory of Environment-Assisted Entanglement Distillation
We evaluate the one-shot entanglement of assistance for an arbitrary bipartite state. This yields another interesting result, namely a characterization of the one-shot distillable entanglement of a bipartite pure state. This result is shown to be stronger than that obtained by specializing the one-shot hashing bound to pure states. Finally, …
