Sergey Yakovlevich Kilin (b. 18.05.1952, Gomel), physicist. Academician of the National Academy of Sciences of Belarus (2014; corresponding member since 2009), Doctor of Physico-Mathematical Sciences (1992), Professor (2006).

Scientific works on quantum optics and quantum informatics. He developed a theory of quantum fluctuations in nonlinear-optical interactions and based on it predicted and explained a number of effects and phenomena observed when photons were emitted by single atoms and molecules in various environments: the grouping effect and anti-grouping of different-frequency photons, freezing of spontaneous decay in photonic crystals, generation squeezed and other nonclassical states in multiphoton processes, the emergence of soliton-like pulses in stimulated Raman scattering, quantum instability awn dipole moment atoms suppression quantum tunneling dynamic laser light monatomic optical bistability in the microcavities. Developed new methods and systems for quantum information technologies. He proposed new schemes and protocols for quantum cryptography and quantum teleportation, proved the advantage of Cubbit coding in comparison with other bases, substantiated a new measure of entanglement of multi-cubic systems, proposed a solution to the problem of decoherence, which represents one of the main obstacles to the creation of quantum processors. He substantiated the possibility of creating a quantum computer and other quantum information devices (quantum follower, quantum memory) based on single nitrogen-vacancy centers (NV centers) in diamond. Under his leadership, the first in the CIS fiber-optic system of quantum cryptography was created. It performs quantum key distribution over a distance of up to ten kilometers based on generation, quantum coding at time intervals, sending and recording quantum bits in the form of single-photon pulses.

Author of more than 460 scientific papers, including 4 monographs.
