    Quantum imaging

    Quantum imaging - a relatively new section of quantum optics, which uses the unique properties of quantum correlations, such as quantum entanglement, in order to obtain images of objects with a resolution or any other image criterion superior to any analogs in classical optics. The experimental quantum imaging schemes developed in the laboratory laboratory of the QPM can serve as the basis for devices: 'ghost' (also two-photon or correlation) imaging quantum lithography imaging with low noise (shot) quantum sensors and other devices. Potentially quantum imaging can be used to store, transfer and process data in quantum computers, as well as to transmit encrypted information.  

    Quantum information theory

    Quantum information theory is one of the most developing sections of modern science. It is at the junction of areas such as quantum physics, information theory and mathematics.   The basic concern in quantum information theory is to estimate the capacity of quantum channels. One of the main areas of research in the laboratory is the analysis of the information properties of various non-classical states of light. For this purporses dissipative dynamics of multimode states models will be constructed, that describe their propagation in various media. Based on such physical models, it will be possible to conduct an information analysis of real quantum channels, which will more accurately describe the operation of various protocols of quantum informatics and evaluate the throughputs of physical quantum channels.

    Quantum optics

    The methods of quantum optics are extremely extensive; they open the way to unique theoretical and experimental research, both fundamental and applied.   Of particular interest are two main areas of research in this area: Firstly, it is a search and description of fundamentally new quantum optical effects, methods for applying useful effects and methods for compensating negative ones. Secondly, it is the development of new mathematical models that describe optical elements that are sometimes well known from the point of view of classical theory in terms of quantum theory in a more accurate way, which allows them to find new, sometimes unexpected, applications, adapt their use to non-classical light.
