  We study the entanglement dynamics between two cavities when one of them is
harmonically shaken in the context of quantum information theory. We find four
different regimes depending on the frequency of the motion and the spectrum of
the moving cavity. If the moving cavity is three dimensional only two modes
inside get coupled and the entanglement can either degrade asymptotically with
time or oscillate depending on the driving. On the other hand, if the cavity
has an equidistant spectrum the entanglement can either vanish asymptotically
if it is driven with its fundamental frequency or have a sudden death if it is
driven with an uneven harmonic frequency.
