Quantum entanglement is the only thing I can think of, since photons certainly CAN be absorbed, reflected and jammed. But entangled pairs would (conceivably, I'm no physicist) accurately report back regardless of what happened to their mates -- if you can tease the information out of them.
My question is WTH are they releasing this information and not locking those researchers up somewhere in the lab of their dreams?
First, given the hints, it's probably an entanglement scheme. Second, the entangled pairs could "report" to each other, but they have only one thing to report: their polarization state. [You can't really entangle the other few quantum numbers of a photon, since they're continuous.] Third, large numbers of entangled photons aren't especially easy to produce and isolate. Sounds like the first feelers of a request for proposal. Maybe the Chinese will fund it.
This is pretty fundamental physics-based research that is presumably not funded by any classified DoD programs. Can’t really be going around and retroactively jailing people for simply having ideas.
Anyway, from reading this, what it seems to be is fundamentally a theoretically possibile way to defeat a specific type of jamming, Digital Radio Frequency Memory (DRFM) I know just enough about Electronic Warfare to be dangerous, but what DRFM does isn’t block or “fuzz” a radar, it generates multiple fake targets that move just like the real target and that can’t be distinguished from the real target.
Any actual “Old Crows” would probably have a better explanation.
