Pentagon's Defense Science Board warns that quantum radar will not be a substantial military improvement

June 21, 2021
Questions about quantum radar have been a concern for some time, given several quantum radar-related announcements made over the last few years.

WASHINGTON – One of the U.S. Department of Defense (DOD), top independent scientific advisory boards has thrown cold water on the many recent predictions that quantum radar will enable new levels of detection far beyond that of traditional radar systems. The Drive reports. Continue reading original article

The Military & Aerospace Electronics take:

21 June 2021 -- Most damning, the Defense Science Board concluded that quantum radar technologies “will not provide upgraded capability to DOD.”

The news isn't all bad for quantum sciences that still offer promise, which include quantum sensing, quantum computers, and quantum communications. Quantum sciences define the way the physical universe works at the subatomic level. Essentially, it's a way of describing how the particles that compose atoms work and interact with one another.

Quantum radar differs from other radar systems because it uses entangled photons to detect objects rather than reflected radio waves. This appears to be true regardless of distance, which may allow for very fast interaction between entangled particles even if the distance between them is very large.
