  We report the results of a direct comparison of a freely expanding turbulent
Bose-Einstein condensate and the propagation of an optical speckle pattern. We
found remarkably similar statistical properties underlying the spatial
propagation of both phenomena. The calculated second-order correlation together
with the typical correlation length of each system is used to compare and
substantiate our observations. We believe that the close analogy existing in
between an expanding turbulent quantum gas and a traveling optical speckle,
might burgeon into an exciting new research field investigating disordered
quantum matter.
