Abstract
This article reviews the extraordinary features of quantum information predicted by the quantum formalism, which, combined with the development of modern quantum technologies, have opened new horizons in quantum physics that can potentially affect various areas of our live, leading to new technologies such as quantum cybersecurity, quantum communication, quantum metrology, and quantum computation.
This review article is based on a lecture on quantum information given at the XLVI Extraordinary Congress of Polish Physicists, Warsaw, Poland, October 16-18, 2020, on the occasion of the centenary of the Polish Physical Society. 37 pages, 4 figures. Minor textual changes, reference added
