Realization of the 1->3 optimal phase-covariant quantum cloning machine
Fabio Sciarrino, Francesco De Martini
The 1->3 quantum phase covariant cloning, which optimally clones qubits belonging to the equatorial plane of the Bloch sphere, achieves the fidelity Fcov(1->3)=0.833, larger than f…
Realization of a General Multi-step Quantum Cloning Machine
L. Masullo, M. Ricci, F. De Martini
A general multi-step N->M probabilistic optimal universal cloning protocol is presented together with the experimental realization of the (1 -> 3) and (2 -> 3) machines. Since the…
Realization of the Optimal Universal Quantum Entangler
Fabio Sciarrino, Francesco De Martini, Vladimir Buzek
We present the first experimental demonstration of the ''optimal'' and ''universal'' quantum entangling process involving qubits encoded in the polarization of single photons. The…
Realization of Universal Optimal Quantum Machines by Projective Operators and Stochastic Maps
F. Sciarrino, C. Sias, M. Ricci +1
Optimal quantum machines can be implemented by linear projective operations. In the present work a general qubit symmetrization theory is presented by investigating the close links…
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…
