    states: ArrayLike,
    *,
    ax: Axes | None = None,

Plot the photon number population of state as a function of time.

Examples

>>> n = 16
>>> a = dq.destroy(n)
>>> psi0 = dq.coherent(n, 0.0)
>>> H = 2.0 * (a + dq.dag(a))
>>> tsave = np.linspace(0, 1.0, 11)
>>> result = dq.sesolve(H, psi0, tsave)
>>> dq.plot_fock_evolution(result.states, times=tsave)

Use the log scale option to visualise low populations:

>>> dq.plot_fock_evolution(result.states, times=tsave, logscale=True)
