Non separable Werner states in spontaneous parametric down-conversion
Marco Caminati, Francesco De Martini, Riccardo Perris +2
The multiphoton states generated by high-gain spontaneous parametric down-conversion (SPDC) in presence of large losses are investigated theoretically and experimentally. The expli…
Experimental realization of a minimal disturbance quantum measurement
F. Sciarrino, M. Ricci, F. De Martini +2
We report the first experimental realization of an ''optimal'' quantum device able to perform a Minimal Disturbance Measurement (MDM) on polarization encoded qubits saturating the…
Separating the classical and quantum information via quantum cloning
M. Ricci, F. Sciarrino, N. J. Cerf +3
An application of quantum cloning to optimally interface a quantum system with a classical observer is presented, in particular we describe a procedure to perform a minimal disturb…
"All-versus-nothing" nonlocality test of quantum mechanics by two-photon hyperentanglement
C. Cinelli, M. Barbieri, R. Perris +2
We report the experimental realization and the characterization of polarization and momentum hyperentangled two photon states, generated by a new parametric source of correlated ph…
Experimental reversion of the optimal quantum cloning and flipping processes
Fabio Sciarrino, Veronica Secondi, Francesco De Martini
The quantum cloner machine maps an unknown arbitrary input qubit into two optimal clones and one optimal flipped qubit. By combining linear and non-linear optical methods we experi…
