We obtained the phase and intensity images of an object by detecting classical light which never interacted with it. With a double passage of a pump and a signal laser beams through a nonlinear crystal, we observe interference between the two idler b

Qudits, d-level quantum systems, have been shown to provide a better resource for quantum key distribution and other Quantum Information protocols. It is customary to generate photonic qudits using more than one degree of freedom of the same photon.

We present the controlled generation of two copies of two-qudit states using four photons and a single degree of freedom, transverse momentum. It is experimentally and theoretically shown that both highly-entangled and separable states were generated

We investigate the single slit diffraction pattern of one- and two-pairs of photons obtained from spontaneous parametric down conversion. Our experimental setup generates two classes of states, Einstein?Podolski?Rosen states and near-separable states

Control of spatial quantum correlations in bi-photons is one of the fundamental principles of Quantum Imaging. Up to now, experiments have been restricted to controlling the state of a single bi-photon, by using linear optical elements. In this work
