Theory of Photo-detection and Quantum Theory of Coherence

It was found possible to develop a mathematical theory of communication which includes quantum effects, and as is also important, reduces to the mathematics of classical communication theory when quantum effects can be neglected. Because photoelectric detection is used universally at optical frequencies, and because it lends itself to a simpler theoretical description, earlier publications have considered the statistics of photo detection - how they differ for coherent and incoherent signals, and the consequences of these differences for information transmission. The work was concentrated in two major areas: (a) statistics of photodetection, and (b) quantum statistical analysis of communication.

It is shown that the canonical correlation method used with the intrinsic degrees of coherence (IDOCs) to describe coherence properties of partially polarized light is effective to identify relevant properties of the photo-detection correlations of a two-photon source described with its density operator. The results are compared with other global correlation measures.
