Prof. Dr. Aleksey Fedorov is a Junior Principal Investigator at the Russian Quantum Center, Professor of Physics at Moscow Institute of Physics and Technology, and founder of startup companies in quantum technologies. His research is related to quantum information technologies and quantum many-body physics. His paper about world-first quantum-secured blockchain was covered in MIT Technology Review, Business Insider, Forbes and put in the list of "the hottest top 5%" of all research outputs by Altmetrics. Aleksey was selected for ’30-under-30’ for Forbes Russia.

Life in our society is suffused with information technologies. Many of our activities — ranging from online shopping and chatting to operating production environments and management systems — are based on collecting, processing, and transmitting data. One of the key aspects in this regard is security. Surely, the history of the problem of ensuring information security is virtually as long as human history. However, for modern society the issue of information security has become truly vital: unauthorized access to various kinds of information could lead to major losses, including financial losses and loss of reputation, for governments and businesses alike.

EPJ E Highlight - Simulating microswimmers in nematic fluids

A combination of two simulation techniques has allowed researchers to investigate how swimming microparticles propel themselves through ‘nematic liquid crystals’ – revealing some unusual behaviours

Artificial microswimmers have received much attention in recent years. By mimicking microbes which convert their surrounding energy into swimming motions, these particles could soon be exploited for many important applications. Yet before this can happen, researchers must develop methods to better control the trajectories of individual microswimmers in complex environments. In a new study published in EPJ E, Shubhadeep Mandal at the Indian Institute of Technology Guwahati (India), and Marco Mazza at the Max Planck Institute for Dynamics and Self-Organisation in Göttingen (Germany) and Loughborough University (UK), show how this control could be achieved using exotic materials named ‘nematic liquid crystals’ (LCs) – whose viscosity and elasticity can vary depending on the direction of an applied force.

EPJ D Topical review - Review of experimental and theoretical research on positronium ions and molecules

Published on 02 July 2021

The relativistic quantum theory developed by Dirac in the 1930’s is the cornerstone of Quantum Electrodynamics (QED), which has proved to be one of the most successful theories in physics. For example, measurements and QED calculations of the anomalous electron magnetic moment agree to 10 significant figures. Physicists now believe that QED can fully account for all effects that are mediated by electromagnetic interactions.
