Toward third order ghost imaging with thermal light
G. Brida, I. P. Degiovanni, G. A. Fornaro +2
Recently it has been suggested that an enhancement in the visibility of ghost images obtained with thermal light can be achieved exploiting higher order correlations [3]. This pape…
Experimental quantum cryptography scheme based on orthogonal states
Alessio Avella, Giorgio Brida, Ivo Pietro Degiovanni +3
Since, in general, non-orthogonal states cannot be cloned, any eavesdropping attempt in a Quantum Communication scheme using non-orthogonal states as carriers of information introd…
Experimental realization of a low-noise heralded single photon source
G. Brida, I. P. Degiovanni, M. Genovese +4
We present a heralded single-photon source with a much lower level of unwanted background photons in the output channel by using the herald photon to control a shutter in the heral…
Detection of multimode spatial correlation in PDC and application to the absolute calibration of a CCD camera
Giorgio Brida, Ivo Pietro Degiovanni, Marco Genovese +2
We propose and demonstrate experimentally a new method based on the spatial entanglement for the absolute calibration of analog detector. The idea consists on measuring the sub-sho…
Biphoton compression in standard optical fiber: exact numerical calculation
G. brida, M. V. Chekhova, I. P. Degiovanni +4
Generation of two-photon wavepackets, produced by spontaneous parametric down conversion in crystals with linearly chirped quasi-phase matching grating, is analyzed. Although being…
