how compute the diffusion constant in a superconductor material in theory?
i mean the rate with which the quasiparticles diffuse in a superconductor material which is radiated with photons.

Not sure what you mean by diffusion constant - this notmally relates to diffusion of gases or liquids.
If you are talking about calculations related to conductivity, then the calssical Drude model relaxation time and hence electron mobility would be infinite.
Because conductivity is infinite, there can be no electric field and so you cannot actually change the current density in a superconductor.
