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?
