    "abstract": "We study analytically and numerically the behavior of quantum entanglement in\na quantum computer operating an efficient algorithm for quantum chaos. Our\nresults show that in an ideal algorithm the entanglement decays exponentially\nwith the diffusive relaxation rate induced by classical chaos. This decay goes\ndown to a residual level which drops exponentially with the number of qubits\nn_q. Decoherence destroys the residual entanglement with a rate exponential in\nn_q.",
