    The paper discusses the importance of information resources requiring reliable methods of unauthorized access protection in the modern information-oriented society. The article describes the structure and basic principles of the quantum cryptography technology based on properties of quantum systems. Quantum information is a physical quantity characterizing changes occurring in the system during interaction between the information flow and the external environment. It offers a method for improving data security and confidential information protection using quantum teleportation within infrared laser communication channels. The theoretical development was implemented experimentally by the authors using the unit for laser communications

We assume that it is possible to achieve this goal based on new forms of cooperation between the main participants: business, state, education, and science. Based on the triple helix model, the study develops a mechanism for cooperation between higher education and business in depressed single-industry regions. The model was tested on the example of the Republic of Kazakhstan. We use the methodological principles of logical, statistical analysis and synthesis. To increase the impact of universities on the national economic growth, we propose a cooperation mechanism based on the Triple Helix model. This model is adapted to the specificity of single-industry and depressed regions, where regional universities play a dominant role as a source of innovation and innovative synergy for the cooperation of partners involved. Simultaneously, the creation of new forms of cooperation between higher education and business leads to the acceleration of social and economic development of regions. The mechanism of the proposed triple helix model aims to encourage all participants to generate innovations, provide high-quality educational services, conduct research and fill business orders. Local and state authorities in the field of economic management can use the results and conclusions of the survey for creating regional development programmes

    Chiral nanoparticles in singular light fields

    The studying of how twisted light interacts with chiral matter on the nanoscale is paramount for tackling the challenging task of optomechanical separation of nanoparticle enantiomers, whose solution can revolutionize the entire pharmaceutical industry. Here we calculate optical forces and torques exerted on chiral nanoparticles by Laguerre–Gaussian beams carrying a topological charge. We show that regardless of the beam polarization, the nanoparticles are exposed to both chiral and achiral forces with nonzero reactive and dissipative components. Longitudinally polarized beams are found to produce chirality densities that can be 10(9) times higher than those of transversely polarized beams and that are comparable to the chirality densities of beams polarized circularly. Our results and analytical expressions prove useful in designing new strategies for mechanical separation of chiral nanoobjects with the help of highly focussed beams
