A Counterfactual Transmission of Information

I saw this paper and would like some comments on it if possible.

That paper is behind a paywall. Someone have an arXiv preprint that's close enough to the final version to substitute?

Really? I'm sorry, someone sent me a link to the Science Alert article and I just clicked the link in that article to the paper itself.

Try this link to the article and then to the paper: http://flip.it/gao4h9

The link in the article is taking me to the same place as the link in your original post: the page at pnas.org with the abstract but not the content of the paper.

At the abstract page just under the authors there is like a menu bar, at the end there is a PDF tab, that takes you to the paper. I tried to upload it but it's too big.

I have this one. It seems to me, information carried by when coherence is broken.

It is an implementation of 10.1103/PhysRevLett.110.170502 (https://arxiv.org/abs/1206.2042). They don't do any measurement to prove the counterfactual claim (that no photons ever travel between Alice and Bob), so it won't help with the debate on whether counterfactual communications are actually possible.

It never hurt to make more independent experiments to rule out a CERN like error, although in this case the setup is way less complex.
