The generation of quantum light from atoms has diverse advantages in addition to its intrinsic resonance with atomic states. On the one hand, it is possible to control the coherence of the light exceptionally, which is attractive to modulate its interaction with atoms. On the other hand, it is also possible to understand the relatively complex mechanisms during the process of the generation itself. The latter has a great potential to provide an exquisite control to print, distribute and read quantum information. In LAFriOC we have extensive experience in the preparation of atomic states. With it, we model and understand experimentally the FWM process to exert control over the entanglement of quantum variables with varying nature such as polarization and angular momentum.
