Photon statistics in the macroscopic realm measured without photon-counters
Alessandra Andreoni, Maria Bondani
In a macroscopic realm, in which photons are too many for being counted by any photon counting detector, photon statistics can be measured by using detectors simply endowed with li…
Demonstration of a bright and compact source of tripartite nonclassical light
Alessia Allevi, Maria Bondani, Matteo G. A. Paris +1
We experimentally demonstrate the nonclassical photon number correlations expected in tripartite continuous variable states obtained by parametric processes. Our scheme involves a…
Light statistics by non-calibrated linear photodetectors
Maria Bondani, Alessia Allevi, Alessandra Andreoni
We theoretically demonstrate that detectors endowed with internal gain and operated in regimes in which they do not necessarily behave as photon-counters, but still ensure linear i…
Experimental joint signal-idler quasi-distributions and photon-number statistics for mesoscopic twin beams
Jan Perina, Jaromir Krepelka, Maria Bondani +2
Joint signal-idler photoelectron distributions of twin beams containing several tens of photons per mode have been measured recently. Exploiting a microscopic quantum theory for jo…
Intensity correlations, entanglement properties and ghost imaging in multimode thermal-seeded parametric downconversion: Theory
Ivo P. Degiovanni, Maria Bondani, Emiliano Puddu +2
We address parametric-downconversion seeded by multimode pseudo-thermal fields. We show that this process may be used to generate multimode pairwise correlated states with entangle…
Sub-shot-noise photon-number correlation in mesoscopic twin-beam of light
Maria Bondani, Alessia Allevi, Guido Zambra +2
We demonstrate sub-shot-noise photon-number correlations in a (temporal) multimode mesoscopic ( detected photons) twin-beam produced by ps-pulsed spontaneous non-degener…
