As quantum systems become more integrated in commercial and industrial technologies, it is only natural to find the limitations of what we can experimentally achieve with regards to these systems. One particular area of interest is the generation of high number Fock states beyond single and pair states. We intend to produce a three photon state via cubic non-linearity in which a pump photon decays into three daughter photons.
We make a theoretical comparison of the expected photon triplet rates, both when the generation of the photon triplet state is spontaneous, and when the process is stimulated by supplying photons in one of the modes of the photon triplet state. By introducing a parameter known as the effective vacuum field it is possible to set-up some general statements about the relative efficiency of each process. By maximising the variables that enter photon triplet rate equation, we suggest several promising materials that can be exploited to generate photon triplets with reasonable rates.
