Laboratory of Topological Quantum Phenomena in Superconducting Systems

Field of research: theoretical and experimental studies of the fundamental physical properties of hybrid superconducting nanostructures, including the development of a quantitative microscopic theory of quantum processes in these systems and its comparison with the results of experiments on tunneling, electronic transport, atomic force, and high-frequency spectroscopy. The objects of research are metal and semiconductor nanostructures based on superconductor contacts with so-called topological insulators.

Physics of "topologically protected" quantum states is a rapidly developing field of science that attracts great interest both in connection with new fundamental effects and because of the prospect of creating fundamentally new types of devices for spintronics and quantum computing. The latter is particularly relevant since, at present, the main problem of implementing quantum computing in advanced laboratories of the world is the loss of quantum coherence due to interaction with the environment. A promising way to solve this problem is to implement topologically protected quantum states (called Majorana fermions) that are resistant to external perturbations and therefore maintain quantum coherence over long periods.

The project goal is to obtain world-class scientific results in the study of topological quantum phenomena in the contacts of superconductors with semiconductor and ferromagnetic nanowires. To publish these results in leading Russian and international journals and develop new quantum mechanical devices. The project will necessarily be accompanied by training of specialists in quantum nanophysics at MIPT and cooperation with Russian and foreign scientists for the development of the national system of science, education, and high technologies.
