    "abstract": "We derive lower bounds for the attainable fidelity of standard entanglement\npurification protocols when local operations and measurements are subjected to\nerrors. We introduce an error parameter which measures the distance between the\nideal completely positive map describing a purification step and the one in the\npresence of errors. We derive non--linear maps for a lower bound of the\nfidelity at each purification step in terms of this parameter.",
