    "abstract": "We present basics of mixed-state entanglement theory. The first part of the\narticle is devoted to mathematical characterizations of entangled states. In\nsecond part we discuss the question of using mixed-state entanglement for\nquantum communication. In particular, a type of entanglement that is not\ndirectly useful for quantum communcation (called bound entanglement) is\nanalysed in detail.",
