My recent scientific interests are concentrated in the following three directions:
--  Quantum  information, communication and computing;
--  Noncommutative probability theory, quantum and classical stochastic processes, quantum Markov property and dynamical semigroups;
--  Statistical structure of quantum theory, quantum measurement.
    A list of selected publications in these directions is given below. For earlier publications comprizing, above the three aforementioned topics, statistics of classical random processes, algebraic approach to quantum theory and applied functional analysis, see  the complete    list of publicationsFor Arxiv e-prints see
Electronic Archive    or the  mirror site in Moscow.
    Quantum information theory is a rich source of difficult
mathematical problems having simple formulation and a profound physical motivation.
