摘要: Abstract In this review we present the main results of some experimental investigations that performed in last 10 years on optical twin-beam states. We explore statistical properties and spatio-spectral coherence different intensity regimes, from mesoscopic to macroscopic domain, also including pump depletion. characterize quantum nature states terms nonclassicality criteria, all them written for detected photons demonstrate generation sub-Poissonian non-Gaussian by conditional operations. Finally, address a ghost-imaging protocol implemented with regime.
