    "abstract": "As a stochastic model for quantum mechanics we present a stationary quantum\nMarkov process for the time evolution of the Wigner function on a lattice phase\nspace Z_N x Z_N with N odd. By introducing a phase factor extension to the\nphase space, each particle can be treated independently. This is an improvement\non earlier methods that require the whole distribution function to determine\nthe evolution of a constituent particle. The process has branching and\nvanishing points, though a finite time interval can be maintained between the\nbranchings. The procedure to perform a simulation using the process is\npresented.",
