Experimental Detection of Quantum Channels    [PDF]

Adeline Orieux, Linda Sansoni, Mauro Persechino, Paolo Mataloni, Matteo Rossi, Chiara Macchiavello
We demonstrate experimentally the possibility of efficiently detecting properties of quantum channels and quantum gates. The optimal detection scheme is first achieved for non entanglement breaking channels of the depolarizing form and is based on the generation and detection of polarized entangled photons. We then demonstrate channel detection for non separable maps by considering the CNOT gate and employing two-photon hyperentangled states.
