摘要：

We show how it is possible to realize quantum computations on a system in which most of the parameters are practically unknown. We illustrate our results with a novel implementation of a quantum computer by means of bosonic atoms in an optical lattice. In particular, we show how a universal set of gates can be carried out even if the number of atoms per site is uncertain.
