The article starts by doing the "quantum" thing that really irks me, where they use confusing terminology to make it sound like "FTL communication" without actually saying it. This is garbage that doesn't actually matter to the article.

Basically, they found a way to send quantum entangled photons (which exist in a very delicate unobserved state) through existing fiber optic infrastructure without interfering with the standard internet information already travelling through the fiber. A lot of the difficulty with this is due to signal noise that needs to be filtered out. This will be useful communicating quantum measurements over long distances.

It should be a legal requirement to link the actual research paper at the top of science articles

I've seen a lot of articles that were like "scientists do this!!" And never link to the actual study (not including this article)

What happened to citing your sources?

2nd paragraph wasn't good enough, huh?

"Only limited by the speed of light..."

They then go on to describe what sounds like

  • transmitting a single specific photon through ‘the internet’, implying start-to-finish with routing (not possible without special infrastructure)

  • Use that photon to then send information instantly by manipulating its entangled sibling (also not possible)

So yeah this article is a crock of shit.

The article did not describe either of those things that way. Cynicism is overriding reading comprehension.
