The problem is that two particles can't communicate with each other when they're arbitrarily close together. The smaller the wavelength of light the greater the energy it has and thus it's mass, remember E =MC^2 so M= E/c^2. Thus at some point the wavelength is so small and the mass is so great that gravitational effects become important and a mini Black Hole is formed with a singularity at its center. Today's physics can't say anything about things smaller than the Plank Length of 10^-33 cm, or anything about time shorter than the time light takes to travel that distance, the Plank Time of 5.4 * 10^-44 sec. On the other hand modern physics can't say anything about what's going on inside the singularity either so perhaps there is some small hope for infinite computation there.
