Continuous variable systems are those described by canonical conjugated coordinates x and p endowed with infinite dimensional hilbert spaces, thus involving a complex mathematical structure. A special class of cv states, are the so-called gaussian states. With them, it has been possible to implement certain quantum tasks as quantum teleportation, quantum cryptography and quantum computation with fantastic experimental success. The importance of gaussian states is two-fold; firstly, its structural mathematical description makes them much more amenable than any other cv system. Secondly, its production, manipulation and detection with current optical technology can be done with a very high degree of accuracy and control. Nevertheless, it is known that in spite of their exceptional role within the space of all continuous variable states, in fact, gaussian states are not always the best candidates to perform quantum information tasks. Thus non-gaussian states emerge as potentially good candidates for communication and computation purposes.<\/p>\n<p>&nbsp;<\/p>\n<h3>Datos acad\u00e9micos de la tesis doctoral \u00ab<strong>Quantum
