The talk reports the current state and prospects of the interdisciplinary field of knowledge - Quantum Information Processing and Computation (QIPC). Basically, QIPC includes three large sections: quantum computation, quantum communications, and quantum information science. The report will consider general and some special issues related to the theoretical and experimental aspects of QIPC mainly related to quantum computation, quantum communications. The focus is on the main technologies of QIPC developed in the world, and especially in the Russian Federation, which potentially lead or have already led to the creation in the near future of quantum simulators and quantum communication systems. In the field of quantum computation/simulators, these are technologies that exploit neutral atoms and ions in traps as working physical systems, superconducting systems, impurity structures, and linear optical systems. In the field of quantum communication - is the creation of a global network based on fiber-optic, atmospheric and space channels. Separately, the main problems of the implementation of certain nodes/elements of the systems of quantum simulators and quantum coupling are considered. In the second part of the talk I will present an overview of the experimental results in the field of quantum computation and quantum coupling, which are held at the Faculty of Physics, within the framework of the Center for Quantum Technologies of the Moscow State University. Prospects for the development of these two areas will be considered in the context of the rapid growth of interest in the world in quantum technologies. On the example of two physical systems - photonic chips and neutral atoms in optical traps, the principles of quantum computation and the main stages in the construction of quantum computers will be presented. In the final part, three particular projects will be presented. These large complex projects are carried out at the MSU Faculty of Physics together with number of partners: - Optical Quantum Simulators; - Development and creation of high-speed quantum encoders; - "Quantum telephone".
