Abstract
Quantum state production and characterization are fundamental elements for many quantum technological applications. In this work, we studied the generation of polarization quantum states by interacting light with a Kerr medium and the dependency of the outcome on orthogonal polarization seedlings. Starting from %Our experimental apparatus is based on coherent states produced by Ti:Sapphire laser, interaction with a ⁸⁷Rb warm vapor cell led to noise compression of -5.2± 0.5 dB (6.4± 0.6 dB after correction of the detection quantum efficiency).
