    "abstract": "We study the pairwise entanglement present in a quantum computer that\nsimulates a dynamically localized system. We show that the concurrence is\nexponentially sensitive to changes in the Hamiltonian of the simulated system.\nMoreover, concurrence is exponentially sensitive to the ``logic\u0027\u0027 position of\nthe qubits chosen. These sensitivities could be experimentally checked\nefficiently by means of quantum simulations with less than ten qubits. We also\nshow that the feasibility of efficient quantum simulations is deeply connected\nto the dynamical regime of the simulated system.",
