    "abstract": "We replace time-averaged entanglement by ensemble-averaged entanglement and\nderive a simple expression for the latter. We show how to calculate the\nensemble average for a two-spin system and for the Jaynes-Cummings model. In\nboth cases the time-dependent entanglement is known as well so that one can\nverify that the time average coincides with the ensemble average.",
