    "abstract": "We investigate quantum information processing and manipulations in disordered\nsystems of ultracold atoms and trapped ions. First, we demonstrate generation\nof entanglement and local realization of quantum gates in a quantum spin glass\nsystem. Entanglement in such systems attains significantly high values, after\nquenched averaging, and has a stable positive value for arbitrary times.\nComplex systems with long range interactions, such as ion chains or dipolar\natomic gases, can be modeled by neural network Hamiltonians. In such systems,\nwe find the characteristic time of persistence of quenched averaged\nentanglement, and also find the time of its revival.",
