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, we show how the one-
shot result yields the operational interpretation of the asymptotic entanglement of assistance
proved by Smolin and coworkers.
