    "abstract": "Motivated by the mathematical definition of entanglement we undertake a\nrigorous analysis of the separability and non-distillability properties in the\nneighborhood of those three-qubit mixed states which are entangled and\ncompletely bi-separable. Our results are not only restricted to this class of\nquantum states, since they rest upon very general properties of mixed states\nand Unextendible Product Bases for any possible number of parties. Robustness\nagainst noise of the relevant properties of these states implies the\nsignificance of their possible experimental realization, therefore being of\nphysical -and not exclusively mathematical- interest.",
