Imprinting a complete information about a quantum channel on its output state
Giacomo Mauro D'Ariano, Paoloplacido Lo Presti
We introduce a novel property of bipartite quantum states, which we call "faithfulness", and we say that a state is faithful when acting with a channel on one of the two quantum sy…
Local observables for entanglement witnesses
G. Mauro D'Ariano, Chiara Macchiavello, Matteo G. A. Paris
We present an explicit construction of entanglement witnesses for depolarized states in arbitrary finite dimension. For infinite dimension we generalize the construction to twin-be…
Exploiting quantum parallelism of entanglement for a complete experimental quantum characterization of a single qubit device
Francesco De Martini, Andrea Mazzei, Marco Ricci +1
We present the first full experimental quantum tomographic characterization of a single-qubit device achieved with a single entangled input state. The entangled input state plays t…
Spin tomography
G. M. D'Ariano, L. Maccone, M. Paini
We propose a tomographic reconstruction scheme for spin states. The experimental setup, which is a modification of the Stern-Gerlach scheme, can be easily performed with currently…
Secure communication using coherent states
Geraldo A. Barbosa, Eric Corndorf, Prem Kumar +4
We demonstrate that secure communication using coherent states is possible. The optimal eavesdropping strategy for an M-ry ciphering scheme shows that the minimum probability of er…
About the use of entanglement in the optical implementation of quantum information processing
M. G. A. Paris, G. M. D'Ariano, P. Lo Presti +1
We review some applications of entanglement to improve quantum measurements and communication, with the main focus on the optical implementation of quantum information processing.…
