  We model quantum transport, described by continuous-time quantum walks
(CTQW), on deterministic Sierpinski fractals, differentiating between
Sierpinski gaskets and Sierpinski carpets, along with their dual structures.
The transport efficiencies are defined in terms of the exact and the average
return probabilities, as well as by the mean survival probability when
absorbing traps are present. In the case of gaskets, localization can be
identified already for small networks (generations). For carpets, our numerical
results indicate a trend towards localization, but only for relatively large
structures. The comparison of gaskets and carpets further implies that,
distinct from the corresponding classical continuous-time random walk, the
spectral dimension does not fully determine the evolution of the CTQW.
