The number of atoms trapped within the mode of an optical cavity is determined in real time by monitoring the transmission of a weak probe beam. Continuous observation of atom number is accomplished in the strong coupling regime of cavity quantum ele

A One-Atom Laser in a Regime of Strong Coupling

Autor: McKeever, J., Boca, A., Boozer, A. D., Buck, J. R., Kimble, H. J.

Publikováno v: Nature 425, 268-271 (2003), supplementary information available at http://www.nature.com/cgi-taf/DynaPage.taf?file=/nature/journal/v425/n6955/abs /nature01974_fs.html

Although conventional lasers operate with a large number of intracavity atoms, the lasing properties of a single atom in a resonant cavity have been theoretically investigated for more than a decade. Here we report the experimental realization of suc

Comparison of Theory and Experiment for a One-Atom Laser in a Regime of Strong Coupling

Autor: Boozer, A. D., Boca, A., Buck, J. R., McKeever, J., Kimble, H. J.

Our recent paper reports the experimental realization of a one-atom laser in a regime of strong coupling (Ref. [1]). Here we provide the supporting theoretical analysis relevant to the operating regime of our experiment. By way of a simplified four-s

State-Insensitive Cooling and Trapping of Single Atoms in an Optical Cavity

Autor: McKeever, J., Buck, J. R., Boozer, A. D., Kuzmich, A., Naegerl, H. -C., Stamper-Kurn, D. M., Kimble, H. J.

Single Cesium atoms are cooled and trapped inside a small optical cavity by way of a novel far-off-resonance dipole-force trap (FORT), with observed lifetimes of 2 to 3 seconds. Trapped atoms are observed continuously via transmission of a strongly c

Optimal Sizes of Dielectric Microspheres for Cavity QED with Strong Coupling

Autor: Buck, J. R., Kimble, H. J.

The whispering gallery modes (WGMs) of quartz microspheres are investigated for the purpose of strong coupling between single photons and atoms in cavity quantum electrodynamics (cavity QED). Within our current understanding of the loss mechanisms of

Experimental Proposal for Achieving Superadditive Communication Capacities with a Binary Quantum Alphabet

Autor: Buck, J. R., van Enk, S. J., Fuchs, Christopher A.

Publikováno v: Phys.Rev.A61:032309,2000

We demonstrate superadditivity in the communication capacity of a binary alphabet consisting of two nonorthogonal quantum states. For this scheme, collective decoding is performed two transmissions at a time. This improves upon the previous schemes o
