  We analyze discrete-time quantum walks on Sierpinski gaskets using a
flip-flop shift operator with the Grover coin. We obtain the scaling of two
important physical quantities: the mean-square displacement and the mixing time
as function of the number of points. The Sierpinski gasket is a fractal that
lacks translational invariance and the results differ from those described in
the literature for ordinary lattices. We find that the displacement varies with
the initial location. Averaged over all initial locations, our simulation
obtain an exponent very similar to classical diffusion.
