    Exactly my thought. I have been considering nanotech tamper proofing of
    small "black boxes". While I think I have some good designs that are
    impervious to material tampering, a gamma ray laser might allow making a
    destructive hologram. The beam hits the black box, disintegrating it,
    but before that a refracted wavefront appears and can be caught on a
    screen, enabling reconstruction of the black box interior. The main
    problem is the wave-particle duality: in order to get the hologram we
    need to get enough photons on the screen to find the pattern, and that
    implies a very high intensity.

    Anybody who knows more about gamma diffraction to give a considered
    opinion?

    I think one way of hiding data better is to hide it in electron spins,
    but that might also show up in the hologram?
