| Abstract | |
Quantum state production and characterization are fundamental elements for many quantum technological applications. In this paper, we studied the generation of polarization quantum states by interacting light with a Kerr medium and the dependency of the outcome on orthogonal polarization seeding. Starting from 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). Experimental characterization of the effect of an orthogonal polarization light seed on squeezing is shown to agree with the theoretical model. (AU) | |
