Examples

>>> psis = [dq.fock(3, i) for i in range(3)]
>>> dq.plot.wigner_mosaic(psis)

>>> n = 16
>>> a = dq.destroy(n)
>>> H = dq.zero(n)
>>> jump_ops = [a @ a - 4.0 * dq.eye(n)]  # cat state inflation
>>> psi0 = dq.coherent(n, 0)
>>> tsave = jnp.linspace(0, 1.0, 101)
>>> result = dq.mesolve(H, jump_ops, psi0, tsave)
>>> dq.plot.wigner_mosaic(result.states, n=6, xmax=4.0, ymax=2.0)

>>> n = 16
>>> a = dq.destroy(n)
>>> H = dq.dag(a) @ dq.dag(a) @ a @ a  # Kerr Hamiltonian
>>> psi0 = dq.coherent(n, 2)
>>> tsave = jnp.linspace(0, jnp.pi, 101)
>>> result = dq.sesolve(H, psi0, tsave)
>>> dq.plot.wigner_mosaic(result.states, n=25, nrows=5, xmax=4.0)
