  Physical implementations of quantum computation must be scrutinized about
their reliability under real conditions, in order to be considered as viable
candidates. Among the proposed models, those based on adiabatic quantum
dynamics have shown great potential for solving specific tasks and have already
been successfully implemented using superconducting devices. In this context,
we address the issue of how the fabrication variations are expected to affect
on average the computation results, when only dynamical effects occur. By
simulating the dynamics of small-scale systems, it is found a considerable
robustness for the computation when analyzing results obtained from ensembles
of such machines. In addition, it is also addressed whether conditions for
adiabaticity could be taken as quantitative measures of it. From the analysis
of four known conditions, it is obtained that none could have such an use.
