    "abstract": "We analyze the effect of a quantum error correcting code on the entanglement\nof encoded logical qubits in the presence of a dephasing interaction with a\ncorrelated environment. Such correlated reservoir introduces entanglement\nbetween physical qubits. We show that for short times the quantum error\ncorrection interprets such entanglement as errors and suppresses it. However\nfor longer time, although quantum error correction is no longer able to correct\nerrors, it enhances the rate of entanglement production due to the interaction\nwith the environment.",
