Cosmological dark energy effects from entanglement
  The thorny issue of relating information theory to cosmology is here
addressed by assuming a possible connection between quantum entanglement
measures and observable universe. In particular, we propose a cosmological toy
model, where the equation of state of the cosmological fluid, which drives the
today observed cosmic acceleration, can be inferred from quantum entanglement
between different cosmological epochs. In such a way the dynamical dark energy
results as byproduct of quantum entanglement.
