No they didn't, they sent a conventional signal that was encrypted with an entangled particle. Nothing was sent ftl, this is like if I had two boxes that I know have the same thing in them, an encryption key, and traveled across the world, and sent you a message, you have the other box, the information in that box didn't go ftl you just opened it later.

there is no path to ftl communication here.

have a basic video on the topic: https://www.youtube.com/watch?v=9oBiS_Yb9Ac

The FTL is the sci-fi component that is the subject of the thread, the quantum entanglement communication part is the real world piece they actually got working.

It will never be possible to use this for ftl communications. This is like saying in 100 years we will use very long steel rods to communicate ftl by pushing on them. The problem is fundamental.
