Futurism reports:

For the first time in the history of quantum mechanics, scientists have been able to transmit a black and white image without having to send any physical particles. The phenomenon can be explained using the Zeno effect, the same effect that explains that movement itself is impossible.

The journal article is in Proceedings of the National Academy of Sciences of the United States of America (DOI: 10.1073/pnas.1614560114)

Wikipedia has an article about the quantum Zeno effect.

    ok, here's the deal: you give me all your fiber, because you can do quantum communication without it, right? I'm dumb and I can only do it with the fiber, but snce you're not using it, can I have all your fiber?

    cpg uses the fiber for classical communication and to stay regular.

    Wrong. The funny thing about this counterfactual imaging is that it only works if you could have sent the light. Basically, you are measuring the reflection of light that you didn't send; but you still need to provide all the optics, even though you're not sending light through it. You sort of send "counterfactual light" through it.
