Quantum internet and prospects of its creation in the near future

Research in the field of quantum physics and electronics, with aim of designing and building quantum devices and quantum Internet, is carried out by scientists from many countries. Recently, the interests of researchers have been directed both to creation of wired networks (by connecting quantum devices via fiber optic cables) and through wireless devices (up to satellites located in Earth orbit). This investigation examines history of quantum devices development and quantum Internet both in foreign countries and in Russian Federation, and provides the diagram of connection between two quantum processors via router. The data on articles, reports and results of workshops (training events) published in scientific journals in bibliographic and abstract database Scopus are analyzed, and graphical dependencies are built on their basis. The data obtained show that interest of scientific community in the topic under consideration has grown significantly over the past decade. The article describes in detail the features, advantages and disadvantages of quantum Internet, which can accelerate the development of new-generation telecommunication networks, improve the research quality and obtain the specific results in this area.
