Entanglement of a microcanonical ensemble
arXiv:quant-ph/0611135 · doi:10.1088/1751-8113/40/10/016
Abstract
We replace time-averaged entanglement by ensemble-averaged entanglement and derive a simple expression for the latter. We show how to calculate the ensemble average for a two-spin system and for the Jaynes-Cummings model. In both cases the time-dependent entanglement is known as well so that one can verify that the time average coincides with the ensemble average.
