Calculating photocount distributions by saddlepoint methods,ed from a physical model of the emissive processes, but inverting them analytically to obtain the distributions of the number of so-called “photocounts” is usually complicated or impossible. Techniques for computing those distributions can be based on numerical evaluation of the inversion integral a

Information in quantum optical communications,The maximum amount of information that a beam can carry is calculated with the use of quantum mechanical methods. Binary communication systems that use these beams are considered and the transmitted information is calculated.

The uncertainty principle in a QND measurement of photon number,the uncertainty principle. As the traditional uncertainty principle involves neither inaccuracy nor disturbance, a new type of uncertainty relation is employed. Self-phase modulation is taken into account, losses are neglected.
