  Most modern classical processors support so-called von Neumann architecture
with program and data registers. In present work is revisited similar approach
to models of quantum processors. Deterministic programmable quantum gate arrays
are considered as an example. They are also called von Neumann quantum
processors here and use conditional quantum dynamics. Such devices have some
problems with universality, but consideration of hybrid quantum processors,
i.e., models with both continuous and discrete quantum variables resolves the
problems. It is also discussed comparison of such a model of quantum processors
with more traditional approach.
