Entanglement, Bunching, and Counting Statistics

We examine the effect of Bernoulli random deletion and additive independent Poisson noise on photon-counting statistics. It is shown that under the action of such deletion and/or noise, both bunched and antibunched distributions move toward the Poisson distribution but never convert from bunched to antibunched or vice versa. Specific calculations are carried out for a number of examples of importance in optics.

We demonstrate time-resolved counting of single atoms extracted from a weakly interacting Bose-Einstein condensate of 87Rb atoms. The atoms are detected with a high-finesse optical cavity and single atom transits are identified. An atom laser beam is formed by continuously output coupling atoms from the Bose-Einstein condensate. We investigate the full counting statistics of this beam and measure its second order correlation function g((2))(tau) in a Hanbury Brown-Twiss type experiment. For the monoenergetic atom laser we observe a constant correlation function g((2))(tau)=1.00 +/- 0.01 and an atom number distribution close to a Poissonian statistics. A pseudothermal atomic beam shows a bunching behavior and a Bose distributed counting statistics.
