Abstract

In the last decades the quantum optics development has been shown an important platform for fundamental tests of quantum mechanics and implementation of quantum information protocols. A source of quantum state of light is needed for most of these implementations. In this project we focus on state generation with polarization squeezing. This can be done using non-linear interation in Rubidium cells. Moreover, we will propose a source of EPR states in polarization.
