So much for stealth if they get this to work.  On the other hand, this might make tracking storms better.

Stealth is already a marketing gimmick.

This concept looks like every other quantum gimmick I've seen... sounds interesting in principle but they handwave aside fundamental problems... like how do you store a microwave pulse without measuring it or having it interact with anything before you do want to measure it?

Blindfolds and no one is allowed to talk about it.

Yeah, the problem is storing the retained photons.  Has to use a delay line (or some other delay mechanism) that delays the retained photons for the same time it takes the emitted photon to reach the target and return, a highly variable time.

Do what my son does:  Use the microwave at 2:00am.

China makes a wild ass claim, western researchers spend years trying to match those claims, China steals the research data. Rinse. Repeat.

Hey, don't blame me.  I voted for "Naugahyde Windpipe".

If I ever need another degree in physics, there's something tangentially related to this that is going to be my thesis.  I kinda hope that never happens, because if I fail ... boo.  If I succeed ... oh shiat.  I'm not telling anyone, and burning down my lab.  Again.

/hell no I'm not reading the article!  Today is my day for commenting without reading.
