    "abstract": "It is shown that if a mixed state can be distilled to the singlet form, it\nmust violate partial transposition criterion [A. Peres, Phys. Rev. Lett. 76,\n1413 (1996)]. It implies that there are two qualitatively different types of\nentanglement: ``free\u0027\u0027 entanglement which is distillable, and ``bound\u0027\u0027\nentanglement which cannot be brought to the singlet form useful for quantum\ncommunication purposes. Possible physical meaning of the result is discussed.",
