Two accelerated observers and degradation of entanglement

We study the entanglement of free scalar and Dirac fields as seen by two accelerated parties. We also study the entanglement distillability of bipartite mixed states of two modes of a free Dirac field, seen by two accelerated parties in the context of Werner states. We conclude that if we considered two accelerated observers instead one, the density matrix would be mixed to a higher degree, resulting in a higher degradation of entanglement.
