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…

Teleportation scheme implementing the Universal Optimal Quantum Cloning Machine and the Universal NOT gate
M. Ricci, F. Sciarrino, C. Sias +1
The universal quantum cloning machine and the universal NOT gate acting on a single qubit can be implemented very generally by slightly modifying the protocol of quantum state tele…
