Could anyone please tell me, how can i plot the Wigner or Q-function for a two-mode squeezed state?I know about single mode squeezed state.

Hi

We don't have any function in QuTiP for calculating two-mode wigner functions. The closest thing we have is the two-mode cross-quadrature correlation distribution, see the class TwoModeQuadratureCorrelation, and some examples in this notebook

Hi all,

It's been a while (11 years...): does anyone know if it is possible to calculate a two-mode "cross wigner function"? Relevant in particular for two-mode squeezed states:

I would also be fine with Q-functions if that is easier

Will look further into this, but would be handy if this was something we could do "out of box"
