Entanglement, EPR correlations and mesoscopic quantum superposition by the high-gain quantum injected parametric amplification
Marco Caminati, Francesco De Martini, Riccardo Perris +2
We investigate the multiparticle quantum superposition and the persistence of multipartite entanglement of the quantum superposition generated by the quantum injected high-gain opt…
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…
Realization of a Decoherence-free, Optimally Distinguishable Mesoscopic Quantum Superposition
Francesco De Martini, Fabio Sciarrino, Veronica Secondi
We report the realization of an entangled quantum superposition of M=12 photons by a high gain, quantum-injected optical parametric amplification. The system is found so highly res…
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…
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…
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…
