The originality of our approach to the above research topics is that we intend to use quantum effects, such as emission and detection of single photons, quantum entanglement etc., as the main tools in the quest for answers to open questions. Some of the outstanding issues that are currently in the focus of our interest are: security and the range of quantum cryptography, holography of objects that do not reflect light, searching for hidden boson particles beyond the Standard Model of particles, generation of random numbers, quantum and quantum-assisted computing. We use and develop a broad variety of experimental techniques, in particular: innovative single-photon detectors, pulsed laser light sources, single and double Fabry-Perot resonators, stabilized continuous single-mode lasers, femtosecond spectroscopy, laser writing, nonlinear effects in homogeneous or periodic nonlinear crystals etc.
