Due to the scientific advances of the last decades, it was possible to build systems with mesoscopic scale. These systems are very useful in research in various areas of science. In mesoscopic physics, the undulating characteristic of electrons becomes more evident comparable to classical physics, so the process of conducting electrons can be represented by the wave function that describes them. In this dissertation, we aim to return the results of Wigner-Dyson to a certain quantum point, using the kwant package made available for Python. In the proposed computational simulation, we will use the Hamiltonian in the Tight - binding method, defined in the kwant package, presenting the data of the numerical simulations for the mean, variance and probability distribution of the Condutance and the firing noise.
