# Quantum Point Process Model for Photodetection

## Abstract

In classical physics, phenomena which involve a random sequence of events in time have been successfully investigated by means of the theory of classical point processes (CPP)[1]. Hence, it is not surprising that most of the theoretical approaches [2–6] to the photon-counting problem are also based on the theory of CPP. The central objective of these investigations is to derive an expression (referred to as the counting formula) for the probability p((t,t+T],m) that m counts are observed in the time interval (t,t+T]. This naturally leads to the study of a situation where the detector performs continuous measurements on the electromagnetic field in the interval (t,t+T].

Another generalisation, which can also be easily carried out, involves replacing (2.5) by the relation where K(r,r’) is sometimes interpreted as a correlation function characterizing the detector. A similar change can also be effected in Egs.(2.9) and (2.18).Google Scholar

However, Davies[10] has indicated how the QPP framework can be suitably generalised in the case of such unbounded Jt.Google Scholar
