Titre : Challenges and Prospects in the Development of Quantum Technologies Auteurs : Laurent Adatto, Revue : Technology and Innovation Numéro : Issue 1 Volume : 8 Date : 2023/01/6 DOI : 10.21494/ISTE.OP.2023.0914 ISSN : 2399-8571 Résumé : This paper analyzes the multiple facets related to the advancement of quantum technologies. To this end, the quantum mechanics necessary for the development of these technologies are first explained from a didactic perspective. Then, investments related to the progress of quantum technologies are shown, in an exhaustive way regarding the French quantum plan, and following elements of comparison concerning the main international plans and developments specific to digital giants. An overview is drawn up, including drivers of material and social progress related to quantum technologies. The potential risks and dangers are also explained, with a particular focus on the cybersecurity aspects of quantum technologies. Thus, guidelines and indicators are developed so that one can better understand the quantum revolution that is taking place and that will, in the near future, be at the root of colossal steps, vectors of gigantic progress, following on from Promethean quantum power.
