| Abstract: | In the present paper the attributes of nonclassical light with respect to the theoretical basis, the experimental verification, and the applications are discussed and compared. If one ore more of the corresponding statistical measures (fluctuation excess, bunching excess, Poisson excess) attain negative values, surprising new properties of photon states occur. The analysis shows that under certain temporal and interaction conditions squeezing, antibunching, and sub-Poisson behavior can accompany one or more of the other attributes. Also the connection of the attributes with the Glauber-Sudarshan P-representation of the corresponding states is studied and yields important assertions. |
