    "abstract": "Bound entanglement is the noisy entanglement which cannot be distilled to a\nsinglet form. Thus it cannot be used alone for quantum communication purposes.\nHere we show that, nevertheless, the bound entanglement can be, in a sense,\npumped into single pair of free entangled particles. It allows for\nteleportation via the pair with the fidelity impossible to achieve without\nsupport of bound entanglement. The result also suggests that the distillable\nentanglement may be not additive.",
