Abstract:
Quantum technology today is in the focus of attention of the scientific community. There has even been put forward such a notion as 'the second quantum revolution'. If the first quantum revolution led to the advent of lasers, transistors and GPS at the beginning of the 20th century, today we are talking about the development of quantum computers, quantum simulators and quantum communication systems. It is believed that the main results of the development of quantum technology will be an unprecedented increase in the performance of computing devices and a qualitatively new level of protection for communication systems. In the first case, we need to solve problems that are inaccessible to classical supercomputers, which is of fundamental importance for producing new materials and preparations, as well as for processing large amounts of data and optimising complex systems. In the second case, the goal is to increase the security of information processing and transmitting to a level that does not depend on the capabilities of eavesdroppers and is determined only by the fundamental laws of physics.
