Kilin, Sergei Yakovlevich (born on May 18, 1952 in Gomel), a physicist. Academician of the National Academy of Sciences of Belarus (2014, Corresponding Member since 2009), Doctor of Physical and Mathematical Sciences (1992), Professor (2006).
Acad. Kilin was educated at the Belarusian State University (graduated in 1974). In 1974 he joined the Physics Institute of the BSSR Academy of Sciences, since 1994 he was head of laboratory. In the meantime since 1992 he was a professor of the Belarusian State University. In 2008 Acad. Kilin was appointed Deputy Academician-Secretary of NASB Department of Physics, Mathematics and Informatics, in 2012 – NASB Chief Scientific Secretary, in 2014 – Deputy Chairman of NASB Presidium.
Acad. Kilin has written research papers on quantum optics and quantum information. He developed the theory of quantum fluctuations in nonlinear optical interactions and on its basis predicted and explained a range of effects and phenomena observed in the emission of photons of single atoms and molecules in different media: the effect of grouping and antigrouping of photons of different frequencies, “freezing” of the spontaneous decay in photonic crystals, generation of compressed and other non-classical states in multiphoton processes, occurrence of soliton-like impulses in stimulated Raman scattering, the quantum instability of the dipole moment of atoms, suppression of quantum dynamic tunneling by laser irradiation, monoatomic optical bistability in microcavities. He developed new methods for quantum information technology. He suggested new schemes and protocols of quantum cryptography and quantum teleportation, proved the advantage of qubit coding in comparison with other bases, justified the new measure of entanglement of multi-qubit systems, proposed the solution to the problem of decoherence, which is one of the main obstacles to creating quantum processors. Acad. Kilin proved the possibility of creating quantum computers and other quantum information devices (quantum repeater, quantum memory) based on single nitrogen-vacancy centers (NV-centres) in the diamond. Under his leadership the first fiber-optical system of quantum cryptography in the CIS was created, which carries out quantum key distribution over a distance of up to ten kilometers on the basis of generation, quantum coding in time slots, transfer and registration of quantum bits in the form of single-photon pulses.
From 2005 to 2011 Acad. Kilin served as Chairman of the Belarusian Physical Society.
He was awarded the Belarus Lenin Komsomol Award (1982) for the article series “Quantum theory of resonance dispersion of laser irradiation”, the Republic of Belarus State Award (2002) for the series “Quantum electrodynamics and coherent nuclear processes in the medium: quantum and nuclear optics”.
Acad. Kilin is the author of more than 460 research papers, including 4 monographs.
