    "abstract": "We investigate how to generate maximally entangled states in systems\ncharacterized by the Hamiltonian of the XXZ model with defects. Some proposed\nquantum computers are described by such model. We show how the defects can be\nused to obtain EPR states and W states when one or two excitations are\nconsidered.",
