Quantum Technology Military Applications and Strategic Implications for Defence — •Michal Krelina — University of Prague

Quantum technologies are emerging as force multipliers for military and intelligence activities by transforming how information is collected, processed, secured and exploited. Near-term applications are most visible in quantum sensing and communications, with implications for navigation and timing in GNSS-denied environments, enhanced submarine and underground detection, improved ISR performance, and highly secure command-and-control links for strategic and high-value assets. These capabilities promise greater resilience and precision, but also challenge existing assumptions about stealth, survivability and situational awareness. Quantum computing, while longer-term, carries profound intelligence implications through its potential to undermine current cryptographic systems, accelerate code-breaking and pattern analysis, and optimise complex military operations and logistics. The uneven pace of quantum adoption across states may generate new asymmetries, compress decision-making timelines and complicate deterrence and escalation dynamics. As quantum technologies converge with AI, cyber and space systems, their military significance will extend beyond individual capabilities to reshape intelligence advantage, operational planning and strategic stability
