    "abstract": "It has been recently pointed out [V. Giovanetti, S. Lloyd, and L. Maccone,\nEurophys. Lett., {\\bf 62} pp. 615-621 (2003)] that, for certain classes of\nstates, quantum entanglement enhances the \"speed\" of evolution of composite\nquantum systems, as measured by the time a given initial state requires to\nevolve to an orthogonal state. We provide here a systematic study of this\neffect for pure states of bipartite systems of low dimensionality, considering\nboth distinguishable (two-qubits) subsystems, and systems constituted of two\nindistinguishable particles.",
