    "abstract": "We present a phase space description of the process of quantum teleportation\nfor a system with an $N$ dimensional space of states. For this purpose we\ndefine a discrete Wigner function which is a minor variation of previously\nexisting ones. This function is useful to represent composite quantum system in\nphase space and to analyze situations where entanglement between subsystems is\nrelevant (dimensionality of the space of states of each subsystem is\narbitrary). We also describe how a direct tomographic measurement of this\nWigner function can be performed.",
