    "abstract": "We represent both the states and the evolution of a quantum computer in phase\nspace using the discrete Wigner function. We study properties of the phase\nspace representation of quantum algorithms: apart from analyzing important\nexamples, such as the Fourier Transform and Grover\u0027s search, we examine the\nconditions for the existence of a direct correspondence between quantum and\nclassical evolutions in phase space. Finally, we describe how to directly\nmeasure the Wigner function in a given phase space point by means of a\ntomographic method that, itself, can be interpreted as a simple quantum\nalgorithm.",
