Examples

>>> rho = dq.coherent_dm(16, 2.0)
>>> dq.plot_hinton(jnp.abs(rho))

plot_hinton_coherent

>>> a = dq.destroy(16)
>>> H = dq.dag(a) @ a + 2.0 * (a + dq.dag(a))
>>> dq.plot_hinton(jnp.abs(H))

plot_hinton_hamiltonian

>>> cnot = [[1, 0, 0, 0], [0, 1, 0, 0], [0, 0, 0, 1], [0, 0, 1, 0]]
>>> dq.plot_hinton(cnot, tickslabel=['00', '01', '10', '11'])

plot_hinton_cnot

>>> key = jax.random.PRNGKey(42)
>>> x = dq.rand_complex(key, (16, 16))
>>> dq.plot_hinton(x)

plot_hinton_rand_complex

>>> _, axs = dq.gridplot(2)
>>> psi = dq.unit(dq.fock(4, 0) - dq.fock(4, 2))
>>> dq.plot_hinton(dq.todm(psi), ax=next(axs))
>>> rho = dq.unit(dq.fock_dm(4, 0) + dq.fock_dm(4, 2))
>>> dq.plot_hinton(rho, ax=next(axs))
