    "abstract": "We investigate entanglement production in a class of quantum baker\u0027s maps.\nThe dynamics of these maps is constructed using strings of qubits, providing a\nnatural tensor-product structure for application of various entanglement\nmeasures. We find that, in general, the quantum baker\u0027s maps are good at\ngenerating entanglement, producing multipartite entanglement amongst the qubits\nclose to that expected in random states. We investigate the evolution of\nseveral entanglement measures: the subsystem linear entropy, the concurrence to\ncharacterize entanglement between pairs of qubits, and two proposals for a\nmeasure of multipartite entanglement. Also derived are some new analytical\nformulae describing the levels of entanglement expected in random pure states.",
