Kesikli wigner fonksiyonu

In the final chapter, through Weyl ordering, continuous Wigner function is derived. Then, using proper assignments, discrete counterpart in discrete phase space is introduced. First computing for single qubit and a pair of qubits, smallest contextual bit qutrit's discrete Wigner function is calculated both for a specific and a general initial condition. For a specific state, it has been shown thatWigner function can indeed have negative values as a quasi-probability distribution. Negative probabilities and their link to contextuality is discussed. As a result, if a qutrit's 6 tables can have at least one negative value for the general initial condition, it will mean that contextuality and negative probabilities are directly linked.
