Today, quantum computing is one of the most promising areas of modern science that can solve the problems which are too hard to handle for classical computers. However, a huge potential accompanied by a rapid progress in this area creates significant ethical risks, including threat of hacking existing cryptographic systems and the problem of non-transparent decisions made using quantum computing. The article highlights the need for timely ethical analysis, development of a regulatory framework, and interdisciplinary collaboration to ensure sustainable and socially acceptable technology development. Main ethical, bioethical challenges, in particular, that arise against the background of quantum computing, and identification of possible ways to regulate them captivate special attention.
