Trapping of single atoms in cavity QED
نویسندگان
چکیده
By integrating the techniques of laser cooling and trapping with those of cavity quantum electrodynamics (QED), single Cesium atoms have been trapped within the mode of a small, high finesse optical cavity in a regime of strong coupling. The observed lifetime for individual atoms trapped within the cavity mode is τ ≈ 28ms, and is limited by fluctuations of light forces arising from the far-detuned intracavity field. This initial realization of trapped atoms in cavity QED should enable diverse protocols in quantum information science.

Trapping of single atoms with single photons in cavity QED
Two recent experiments have reported the trapping of individual atoms inside optical resonators by the mechanical forces associated with single photons @Hood et al., Science 287, 1447 ~2000!; Pinkse et al., Nature ~London! 404, 365 ~2000!#. Here we analyze the trapping dynamics in these settings, focusing on two points of interest. First, we investigate the extent to which light-induced forces ...

This work is about the implementation of quantum information processing in the realm of cavity QED. The first part deals with trapping an atom in a cavity, the second part discusses the utilization of an atom as a source of entangled flying qubits and the third part turns to multi-atom effects. The aim of the first part is to find ways to trap an atom in a cavity. In contrast to other approache...
