    "abstract": "We study quantum feedback cooling of atomic motion in an optical cavity as a\nprototypical nonlinear quantum control problem. We design a feedback algorithm\nthat can cool the atom to the ground state of the optical potential with high\nefficiency despite the nonlinear nature of this problem. An important\ningredient is a simplified state-estimation algorithm, necessary for a\nreal-time implementation of the feedback loop. We also describe the critical\nrole of parity dynamics in the cooling process and present a simple theory that\npredicts the achievable steady-state atomic energies.",
