    "abstract": "In open quantum systems, entanglement can vanish faster than coherence. This\nphenomenon is usually called sudden death of entanglement. In this paper sudden\ndeath of entanglement is discussed from a geometrical point of view, in the\ncontext of two qubits. A classification of possible scenarios is presented,\nwith important known examples classified. Theoretical and experimental\nconstruction of other examples is suggested as well as large dimensional and\nmultipartite versions of the effect.",
