    "abstract": "A general multi-step N-\u003eM probabilistic optimal universal cloning protocol is\npresented together with the experimental realization of the (1 -\u003e 3) and (2 -\u003e\n3) machines. Since the present method exploits the bosonic nature of the\nphotons, it can be applied to any particle obeying to the Bose statistics. On a\ntechnological perspective, the present protocol is expected to find\napplications as a novel, multi-qubit symmetrizator device to be used in modern\nquantum information networks.",
