The experiment I heard about had a pair of photons created from electron-
positron annihilation. The photons have equal energy and speed and exactly
opposite velocity. The experiment attempted to measure the energy of one
photon and ?position of the other. Since the photons are paired, if the
measurements are possible, uncertainity is defeated.

As it turned out, measuring one photon perturbed the other apparently
instanteously. Thus the LOSS of information might propagate with arbitrary
speed.

The question is, can the loss of information itself be information? Someone
was suppose to look into it, but I have never heard any more.
