Defense Primer: Quantum Technology

Quantum technology translates the principles of quantum physics into technological applications. In general, quantum technology has not yet reached maturity; however, it could hold significant implications for the future of military sensing, encryption, and communications, as well as for congressional oversight, authorizations, and appropriations.

The Defense Science Board (DSB), an independent DOD board of scientific advisors, has concluded that three applications of quantum technology hold the most promise for DOD: quantum sensing, quantum computers, and quantum communications. The DSB concluded that quantum radar, hypothesized to be capable of identifying the performance characteristics (e.g., radar cross-section, speed) of objects— including low observable, or stealth, aircraft—“will not provide upgraded capability to DOD.” Read more quantum technology and what the advancements could do for the military’s future.
