scqubits.Cos2PhiQubit.plot_potential# Cos2PhiQubit.plot_potential(phi_grid=None, theta_grid=None, contour_vals=None, **kwargs)[source]# Draw contour plot of the potential energy in \(\theta, \phi\) basis, at \(\zeta = 0\) Parameters: phi_grid (Grid1d, option) – used for setting a custom grid for phi; if None use self._default_phi_grid theta_grid (Grid1d, option) – used for setting a custom grid for theta; if None use self._default_theta_grid contour_vals (list, optional) – **kwargs – plotting parameters Return type: Tuple[Figure, Axes]
