    "abstract": "We discuss the effect of a single diagonal defect on both the static and\ndynamical properties of entanglement in a spin chain. We show that entanglement\nlocalizes at the defect and discuss its localization length, arguing that this\ncan be used as a mean to store entanglement. We also show that the impurity\nsite can behave as an entanglement mirror and characterize the bouncing process\nin terms of reflection and transmission coefficients.",
