We will use the four wave mixing process and the electromagnetically induced transparency in the cold atomic vapor of a magneto-optical trap for the generation of entangled fields from coherent states produced from a Ti:sapphire laser. Beyond this process, we will use the entanglement of the beams produced by an optical parametric oscillator in the interaction with optical transitions in alkaline atoms, looking for the entanglement between the atomic system and part of the output fields from an OPO. For this purpose, we will develop an OPO pumped at 780 nm by a Ti: sapphire laser, in resonance with the D2 line of rubidium atoms (AU)
