Role of seeding in the generation of polarization squeezed light by atomic Kerr medium

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).
