Abstract
Quadratic stochastic processes describe the physical systems defined above, but they do not cover the cases at a quantum level. So, it is natural to define a concept of a quantum quadratic process. In this chapter we will define a quantum (noncommutative) analogue of quadratic stochastic processes. In our case, such a process will be defined on a von Neumann algebra, and we will study its ergodic properties such as the ergodic principle, regularity, etc. From the physical point of view, such a principle means that for sufficiently large values of time a system described by the process does not depend on the initial state of the system.
