Quantum technology as a determinant of technological sovereignty and cybersecurity of the European Union

Over the past decades, a gradual technological marginalisation of Europe could be observed, as it became dependent on imports of advanced microchips from the United States and Taiwan. However, despite planned investments in the development and production of semiconductors in the EU Member States, Europe is still unlikely to be able to compete with the United States and China in this area. The solution to this problem may lie within quantum technology, the economic use of which is in the initial phase in all world centres. The performance of quantum computing surpasses algorithms used in silicon technology by several tens of orders of magnitude. This means that access to quantum technology will become a basic determinant of security in the coming years. The aim of this paper is to present the issue of quantum technology and its most important implicationsin the context of the technological sovereignty of the European Union.
