Minimum Total Noise in Wave-Mixing Processes

الملخص EN

Higher-order squeezing in different optical processes such as seven-wave mixing and five-wave mixing has been studied.

The total noise of a field state is a measure of the fluctuations of the field amplitude.

It is shown that the minimum total noise (Tmin) of a higher-order squeezed state always increases with the increase in nonclassicality associated with higher-order squeezing.

Thus, from Tmin, one can conclude that highly nonclassical states have large amplitude fluctuations.
