1943– · Quantum information, Mathematical physics

Russian mathematician and physicist, one of the pioneers of quantum information theory. He proved the theorem on the capacity of a quantum channel (the Holevo bound), which determines the maximum amount of classical information that can be extracted from a quantum state. His works laid the foundations of quantum communication and cryptography.

Biography

He graduated from the Moscow Institute of Physics and Technology (MIPT). He works at the Steklov Mathematical Institute of the Russian Academy of Sciences. He is a winner of international awards, including the Shannon Award (2016) and the Dirac Medal (2025, jointly). He is a corresponding member of the Russian Academy of Sciences. He is the author of the fundamental monograph 'Introduction to Quantum Information Theory'.

Key discoveries

Holevo bound: established an upper limit on the amount of accessible classical information from quantum measurements (1973).
Quantum estimation theory: developed methods for optimal processing of quantum information.
Quantum channel capacity: made decisive contributions to the analysis of the capabilities of quantum communication channels.

💡 Holevo is one of the most cited Russian scientists in quantum information. His bound is often compared to Shannon's capacity in classical information theory.

Quote: ""Quantum information is not just information encoded in quantum states; it is a new resource that surpasses the classical one.""
