    "abstract": "We present a general description of separable states in Quantum Mechanics. In\nparticular, our result gives an easy proof that inseparabitity (or\nentanglement) is a pure quantum (noncommutative) notion. This implies that\ndistinction between separability and inseparabitity has sense only for\ncomposite systems consisting of pure quantum subsystems. Moreover, we provide\nthe unified characterization of pure-state entanglement and mixed-state\nentanglement.",
