Abstract

We propose a method for implementing digital-optical arithmetic with high accuracy at extremely high speed. To this end we use the superposition of photons running through a passive network of simple optical components. All possible solution are realized in parallel by superposition. Therefore, the overall computing time can be reduced to the sum of the time of flight through a very short optical path and the time needed for input and output.
