    "abstract": "We consider entanglement distillation from a single-copy of a multipartite\nstate, and instead of rates we analyze the \"quality\" of the distilled\nentanglement. This \"quality\" is quantified by the fidelity with the GHZ-state.\nWe show that each not fully-separable state $\\sigma$ can increase the \"quality\"\nof the entanglement distilled from other states, no matter how weakly entangled\nis $\\sigma$. We also generalize this to the case where the goal is distilling\nstates different than the GHZ. These results provide new insights on the\ngeometry of the set of separable states and its dual (the set of entanglement\nwitnesses).",
