    "abstract": "Local Operations enhancing the entanglement of bipartite quantum states are\nof great interest in quantum information processing. Subject of this paper are\nlocal selective operations acting on single copies of states. Such operations\ncan lead to larger entanglement with respect to a certain measure as studies\nbefore by the Horodeckis and A. Kent et al. (PRA 60,PRL 81 and 83). We present\na complete characterisation of all local operations yielding optimal\nentanglement for pairs of qubits, extending former results of A. Kent et al. We\nintroduce a new technique for the classification of states according to their\nbehaviour under entanglement optimizing operations, using the entanglement\nproperties of the support of density matrices.",
