Free-space quantum key distribution by rotation-invariant twisted photons
Giuseppe Vallone, Vincenzo D'Ambrosio, Anna Sponselli +4
Twisted photons are photons carrying a well-defined nonzero value of orbital angular momentum (OAM). The associated optical wave exhibits a helical shape of the wavefront (hence th…
Experimental optimal cloning of four-dimensional quantum states of photons
Eleonora Nagali, Daniele Giovannini, Lorenzo Marrucci +3
Optimal quantum cloning is the process of making one or more copies of an arbitrary unknown input quantum state with the highest possible fidelity. All reported demonstrations of q…
Experimental quantum process tomography of non trace-preserving maps
I. Bongioanni, L. Sansoni, F. Sciarrino +2
The ability of fully reconstructing quantum maps is a fundamental task of quantum information, in particular when coupling with the environment and experimental imperfections of de…
Quantum to classical transition via fuzzy measurements on high gain spontaneous parametric down-conversion
C. Vitelli, N. Spagnolo, L. Toffoli +2
We consider the high gain spontaneous parametric down-conversion in a non collinear geometry as a paradigmatic scenario to investigate the quantum-to-classical transition by increa…
Polarization control of single photon quantum orbital angular momentum states
E. Nagali, F. Sciarrino, F. De Martini +4
The orbital angular momentum of photons, being defined in an infinitely dimensional discrete Hilbert space, offers a promising resource for high-dimensional quantum information pro…
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…
