Given some quantum state $\rho$, I would like to plot its Wigner function. Taking some examples, the Wigner function for number states, coherent states are well known, but it is not clear how one can plot it.
One solution is to truncate the Fock space of the state and find an analytic expression for the Wigner function that can be plotted. Alternatively, and what I am seeking, it can be plotted using a stochastic trajectory approach which samples the distribution. However, I am unsure on how to plot it. Any help would be appreciated!
I would like to plot the Wigner functions for a thermal state, coherent state, displaced coherent states and squeezed thermal states.
