Intensity correlations, entanglement properties, and ghost imaging in multimode thermal-seeded parametric down-conversion: Theory

摘要: We address parametric down-conversion seeded by multimode pseudothermal fields. show that this process may be used to generate pairwise correlated states with entanglement properties can tuned controlling the seed intensities. Parametric fields represents a source of states, which allows one explore classical-quantum transition in correlations and realize ghost imaging diffraction regimes not yet explored experiments.
