If we consider for example a quantum computer, which uses quantum interactions for calculations, would there be an upper limit to its speed (besides the obvious limitations of the setup)?

That may be true for a rod, but 'size' for a fundamental particle is somewhat fuzzy, isn't it?

Is there a minimum time interval for two fundamental particles to interact, or is the interaction instantaneous? For example, if a photon excites an electron, is there a time period required for this interaction to take place? When a billiard ball hits another one there is obviously a time...
