Quantum for National Security
Quantum Innovation Driving Strategic Defense Superiority
Quantum technology is a critical tool for advancing national security. From securing communications, to enabling breakthroughs in sensing and navigation, quantum innovations are reshaping how the U.S., UK, Australia, and allies defend their interests, remain ahead of evolving global threats, and maintain strategic advantage.
Resilient Positioning, Navigation, and Timing (PNT)
Modern defense systems rely on GPS/GNSS, but adversaries are increasingly able to spoof and jam them. Quantum technologies such as optical atomic clocks, quantum radiofrequency (RF) receivers, and quantum inertial sensors offer a path to GPS/GNSS-independent navigation and timing. These tools ensure continuity of operations in contested environments—from aircraft and naval vessels to critical national infrastructure.
Intelligence, Surveillance, and Reconnaissance (ISR)
National security requires the ability to detect threats that remain invisible to conventional technologies. Quantum RF receivers and gravimetric sensors can sense signals and underground structures that are invisible to conventional technologies. These breakthroughs enhance situational awareness, threat detection, and electronic warfare capabilities.
Secure Communications & Cyber Defense
Traditional radio communication systems can be jammed or intercepted by adversaries. Infleqtion’s Sqywire quantum RF receiver leverages Rydberg atoms to detect extremely weak signals across a wide spectrum. Its ability to rapidly hop across frequencies makes communications harder to detect or disrupt, while its compact design enables low-power, covert, and resilient connectivity in contested environments.
Space & Strategic Systems
Space has the potential to become a highly contested environment. Quantum sensors and clocks deployed on satellites will strengthen space domain awareness, resilient navigation, and inter-satellite synchronization. In addition, space-based quantum technologies will enable advances in earth observation and signals intelligence. These advances will protect strategic assets and improve the resilience of global defense infrastructure.
From Research to Deployment
Quantum technologies have matured from research concepts into deployable systems, and national security institutions are now rapidly investing behind programs to procure mission-ready products. The path from laboratory to battlefield is accelerating, and quantum is now increasingly central to national security roadmaps.
