  A Knill-Laflamme-Milburn (KLM) type quantum computation with bosonic neutral
atoms or bosonic ions is suggested. Crucially, as opposite to other quantum
computation schemes involving atoms (ions), no controlled interactions between
atoms (ions) involving their internal levels are required. Versus photonic KLM
computation this scheme has the advantage that single atom (ion) sources are
more natural than single photon sources, and single atom (ion) detectors are
far more efficient than single photon ones.
