    "abstract": "Recent realizations of single-atom trapping and tracking in cavity QED open\nthe door for feedback schemes which actively stabilize the motion of a single\natom in real time. We present feedback algorithms for cooling the radial\ncomponent of motion for a single atom trapped by strong coupling to\nsingle-photon fields in an optical cavity. Performance of various algorithms is\nstudied through simulations of single-atom trajectories, with full dynamical\nand measurement noise included. Closed loop feedback algorithms compare\nfavorably to open-loop \"switching\" analogs, demonstrating the importance of\napplying actual position information in real time. The high optical information\nrate in current experiments enables real-time tracking that approaches the\nstandard quantum limit for broadband position measurements, suggesting that\nrealistic active feedback schemes may reach a regime where measurement\nbackaction appreciably alters the motional dynamics.",
