    "abstract": "We consider the change of entanglement of formation $\\Delta E$ produced by a\nunitary transformation acting on a general (pure or mixed) state $\\rho$\ndescribing a system of two qubits. We study numerically the probabilities of\nobtaining different values of $\\Delta E$, assuming that the initial state is\nrandomly distributed in the space of all states according to the product\nmeasure introduced by Zyczkowski {\\it et al.} [Phys. Rev. A {\\bf 58} (1998)\n883].",
