    "abstract": "A general protocol in Quantum Information and Communication relies in the\nability of producing, transmitting and reconstructing, in general, qunits. In\nthis letter we show for the first time the experimental implementation of these\nthree basic steps on a pure state in a three dimensional space, by means of the\norbital angular momentum of the photons. The reconstruction of the qutrit is\nperformed with tomographic techniques and a Maximum-Likelihood estimation\nmethod. In this way we also demonstrate that we can perform any transformation\nin the three dimensional space.",
