  We analyze how entanglement is generated and distributed in a Bhabha
scattering process $(e^-e^+\rightarrow e^-e^+)$ at tree level. In our setup an
electron $A$ scatters with a positron $B$, which is initially entangled with
another electron $C$ (spectator), that does not participate directly to the
process. We find that the QED scattering generates and distributes entanglement
in a non-trivial way among the three particles: the correlations in the output
channels $AB$, $AC$ and $BC$ are studied in detail as functions of the
scattering parameters and of the initial entanglement weight. Although derived
in a specific case, our results exhibit some general features of other similar
QED scattering processes, for which the extension of the present analysis is
straightforward.
