Sub-shot-noise photon-number correlation in mesoscopic twin-beam of light
arXiv:quant-ph/0612198 · doi:10.1103/PhysRevA.76.013833
Abstract
We demonstrate sub-shot-noise photon-number correlations in a (temporal) multimode mesoscopic ( detected photons) twin-beam produced by ps-pulsed spontaneous non-degenerate parametric downconversion. We have separately detected the signal and idler distributions of photons collected in twin coherence areas and found that the variance of the photon-count difference goes below the shot-noise limit by 3.25 dB. The number of temporal modes contained in the twin-beam, as well as the size of the twin coherence areas, depends on the pump intensity. Our scheme is based on spontaneous downconversion and thus does not suffer from limitations due to the finite gain of the parametric process. Twin-beams are also used to demonstrate the conditional preparation of a nonclassical (sub-Poissonian) state.
