| Abstract: | In many nonlinear optical problems, for example in down-conversion and four-wave mixing, the photons are generated in pairs.
The strong correlation between the photons in a pair, characterized by either the correlations between operators corresponding
to observables associated with individual photons, or the correlated state describing the two photons, may lead to various
nonclassicalities. We discuss some of these nonclassical effects and their experimental demonstrations in nonlinear optical
processes |
