Abstract :
Summary form only given. The dynamics in a parametric /spl chi//sup (2)/ crystal is described by an operator which is proportional to the interaction-time, the nonlinear susceptibility, and the pump intensity. The output state from the downconversion process is given by twin-beams. If one of the two beams is detected by an avalanche ON/OFF photodetector the outcomes "1", i.e registering a "click" corresponding to one or more incoming photons occur with a given probability dependent on the quantum efficiency.
