Abstract
We study the possibility of preventing finite-time disentanglement caused by dissipation by making use of "non-local quantum error correction. This is made in comparison of previous results, where was shown that "local" quantum error correction can delay disentanglement, but can also cause entanglement sudden death when is not originally present.
