    "abstract": "Qubit networks with long-range interactions inspired by the Hebb rule can be\nused as quantum associative memories. Starting from a uniform superposition,\nthe unitary evolution generated by these interactions drives the network\nthrough a quantum phase transition at a critical computation time, after which\nferromagnetic order guarantees that a measurement retrieves the stored memory.\nThe maximum memory capacity p of these qubit networks is reached at a memory\ndensity p/n=1.",
