  The name of John von Neumann is common both in quantum mechanics and computer
science. Are they really two absolutely unconnected areas? Many works devoted
to quantum computations and communications are serious argument to suggest
about existence of such a relation, but it is impossible to touch the new and
active theme in a short review. In the paper are described the structures and
models of linear algebra and just due to their generality it is possible to use
universal description of very different areas as quantum mechanics and theory
of Bayesian image analysis, associative memory, neural networks, fuzzy logic.
