Quantum information theory is a rapidly developing branch of physics. It is based upon the principles of quantum mechanics, which are quite different from intuitive laws of classical physics. Results of the current research allow to hope that it will be possible to construct quantum computers with computational speeds considerably exceeding those of the contemporary ones.

Quantum entanglement plays essential role both in the theory and in experiment. 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 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 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.

It 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 surroundings.

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 new ideas and discoveries.

Lastly, 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 of Gdańsk University.

Experiments will include spectroscopic characterization of the materials for quantum processing, especially if they could allow down-conversion effect (the most versatile source of entanglement). Materials suitable for persistent luminescence and information storage will be studied. Finally the experiment effort will also be focused on the research on excitation energy and polarization transfer in nanolayers. Some of these studies may have potential applications also in the techniques which are outside quantum information processing.
