The report analyzes the current state of the problem of creating a quantum computer as a real working device, which the world scientific community identifies as one of the most important fundamental tasks of physics in the XXI century. It is emphasized that the work of the quantum computer is based on the results of basic research in the field of quantum physics. Today, the world is actively developing quantum technologies, which are expected to be implemented in the near future and provide breakthrough results in many areas of public life: from cryptography to modeling large-scale systems, description and prediction of complex processes and more. The contribution of Ukrainian scientists to the study of quantum systems, the development of quantum technologies and the solution of physical problems that arise in the implementation of elements of the quantum computer is considered.
