Realization of an Optimally Distinguishable Multi-photon Quantum Superposition
Francesco De Martini, Fabio Sciarrino
We report the successful generation of an entangled multiparticle quantum superposition of pure photon states. They result from a multiple (universal} cloning of a single photon qu…
Nonlocality tests of Bell Inequalities and of Hardy's "ladder theorem" without "supplementary assumptions"
M. Barbieri, F. De Martini, G. Di Nepi +1
We have experimentally tested the non local properties of the states generated by a high brilliance source of entanglement which virtually allows the direct measurement of the full…
Experimental realization of hyper-entangled two-photon states
C. Cinelli, M. Barbieri, F. De Martini +1
We report on the the experimental realization of hyper-entangled two photon states, entangled in polarization and momentum. These states are produced by a high brilliance parametri…
A Qubit on the Faraday Mirror
F. De Martini, F. Sciarrino, V. Secondi
In the context of Quantum Information (QI) the ''Faraday Mirror'' acts as a non-universal NOT Gate. As such its behaviour complies with the principles of quantum mechanics. This no…
