The violation of a\nBell inequality has been tested for the first time with a pure-state, indeed a\nconceptually relevant ideal condition, and with Werner-states. The generalized\n\u0027\u0027maximally entangled mixed states\u0027\u0027 (MEMS) were also synthetized for the first\ntime and their exotic properties investigated by means of a quantum tomographic\ntechnique.",
