517.958, 530.145
Subject:
1. Mathematical foundations of theory of open quantum systems: derivation of quantum master equations, asymptotic properties of solutions of the Gorini–Kosssakowski–Sudarshan–Lindblad (GKSL) equation, applications to quantum biology and quantum thermodynamics. The general focus is on mathematically rigorous results on challenging problems in theoretical physics.
2. Quantum key distribution: security proofs of quantum key distribution with imperfect devices (i.e., for the practical case), quantum networks.
The most important results:
In the field of mathematical foundations of statistical mechanics and irreversibility:
The existence of microscopic (singular) solutions of the nonlinear integro-differential Boltzmann–Enskog kinetic equation has been proved (with M. Pulvirenti and S. Simonella). These solutions were discovered by N. N. Bogolyubov on the physical level of rigour and are important for understanding the correspondence between the reversible microscopic dynamics and irreversible macroscopic dynamics.
In the field of quantum key distribution:
Security of the most widely used BB84 protocol with detection-efficiency mismatch has been proved. This case is practical and significantly more mathematically challenging. The main mathematical difficulty was to obtain estimates for quantum entropic quantities in an infinite-dimensional space. This result is included in the list of the most important achievements of the Russian scientists in the field of mathematics in 2020.
In the field of mathematical foundations of the theory of open quantum systems:
Based on the perturbation theory, the local approach to quantum master equations has been rigorously justified (with I. V. Volovich). This result is important because the local approach is simple and widely used in theoretical physics, but had not rigorous justification.
The unified quantum master equation for the weak system-bath coupling regime beyond the secular approximation has been rigorously derived. This was a known fundamental problem in this field.
Biography
Graduated from Moscow Engineering Physics Institute with honours in 2006 (Faculty of Cybernetics, Department of System Analysis). Post-graduate education in the Steklov Mathematical Institute of Russian Academy of Sciences (Department of Mathematical Physics, supervisor Prof. Igor Volovich). Ph.D. (2009), habilitation (2020). Now I am a leading researcher in the Steklov Mathematical Institute of Russian Academy of Sciences (Department of Mathematical Physics), professor of Moscow Institute of Physics and Technology and of National University of Science and Technology MISIS. In 2023–2025, I work in the project "Quantum networks: Correlations and Communication" in the Heinrich Heine University Düsseldorf (working group of Prof. Dagmar Bruß).
Laureate of grants of the presidential program for young scientists in Russia. Scientific results on quantum key distribution have been included in the list of the most important achievements of the Russian scientists in the field of mathematics in 2020. Award of the Government of Moscow for Young Scientists in Mathematics, Mechanics, and Computer Science in 2022 for the proof of security of quantum cryptography with practical devices.
Teaching: courses on quantum computations, quantum key distribution, information theory and mathematical modelling. I have supervised four masters theses.
