Quantum information theory is a rapidly developing branch of physics. There are, for example, safe communication protocols which exclude eavesdropping. Security of communication does not depend on the ingenuity od ciphering, it is due to the laws of nature -- principles of quantum mechanics, the rules of which are quite different from intuitively obvious laws of classical physics. Results of the current research allow us to hope that it will be possible to construct quantum computers with computational speeds considerably exceeding those of the contemporary computers.


The project has definitely scientific character. We plan to conduct fundamental and highly specialized research on the techniques of information manipulation by the methods stemming from principles of quantum mechanics.


Quantum entanglement plays essential role both in the theory and in experiment. The phenomenon of entanglement is known since Schroedinger times. Only recently it was realized that it is a fundamental resource of quantum information theory. Large part of the planned research will be devoted to further studies of entanglement both experimentally and theoretically. New methods to produce and detect the entangled states will be sought. This requires a close cooperation between theoreticians and experimentalists. This will be accomplished by wide collaboration with foreign laboratories which possess the "state of the art" most advanced equipment.


Another important goal is to investigate the properties of the entangled states which ensure the safe communication and information exchange. This is connected with the study of various correlations, frequently yet unknown and never existing in the realm of classical physics. Study of such correlations has practical implications in secure information transfer. They also have fundamental importance - in quantum probabilistic theory.


In must be remembered that every physical system interacts with its environment. Such interactions result in the decay of correlations. Since the latter are so essential the analysis of such decays needs to be investigated. Moreover, the ways to circumvent the losses due to the surrounding. It seems reasonable to say, that the number of questions
concerning quantum entanglement is indeed large.
Therefore the project addresses a multitude of problems. It is also possible that new developments will open completely new and unexpected vistas which will lead to fascinating new ideas and discoveries.


Last, but not least, the project has a distinctive experimental aspect. New materials are essential in new technologies and applications of quantum information theory. Production and detection of the entangled states is not easy. New, effective materials, hopefully with precisely tailored properties, will be synthesized and investigated. The purchase of new devices is planned to enhance the experimental capabilities
