Universal ultrabright source of entangled photon states: generation and tomographic analysis of Werner states and of Maximally Entangled Mixed States
G. Di Nepi, F. De Martini, M. Barbieri +1
A novel ultrabright parametric source of polarization entangled photon pairs with striking spatial characteristics is reported. The distribution of the output electromagnetic k-mod…
Experimental Detection of Entanglement with Polarized Photons
M. Barbieri, F. De Martini, G. Di Nepi +3
We report on the first experimental realization of the entanglement witness for polarization entangled photons. It represents a recently discovered significant quantum information…
Violation of Bell inequalities and Quantum Tomography with Pure-states, Werner-states and Maximally Entangled Mixed States created by a Universal Quantum Entangler
M. Barbieri, F. De Martini, G. Di Nepi +1
Entangled pure-states, Werner-states and generalized mixed-states of any structure, spanning a 2x2 Hilbert space are created by a novel high-brilliance universal source of polariza…
