Abstract

Technologies based on quantum mechanics—such as superposition, entanglement, and interference—are driving a technological race with direct implications for security and defense. Quantum computers, unbreakable cryptography, and ultra-sensitive sensors are already part of the military strategies of major powers such as the United States, China, and the European Union. This article analyzes the role of quantum technologies in the geopolitical dispute between these powers and their possible impacts on Brazil's defense. The research adopts a qualitative approach, with a case study, literature review, and scenario analysis, based on specialized sources. The data were obtained through secondary research in specialized defense sources. The results indicate that mastering these technologies already generates strategic advantages, especially in improving command, control, communications, computing, and reconnaissance (C4ISR) capabilities. They expand the reach of cyber warfare, challenge current encryption systems, allow the detection of stealth threats and revolutionize navigation in GPS-denied environments. In Brazil, although still far from global leadership, strategic applications are foreseen in the field of protecting the Amazon, borders and military communications. It is concluded that quantum technologies represent risks and opportunities. Consistent investments, international partnerships and innovation policies are essential to position Brazil as a relevant player in this emerging field.
