FTL Communications?

It looks interesting. The holdup for FTL communications across stellar distances would be the entangled pairs. Once created, they would still need to the separated and one half carried off to the other end. And, unless I misremember, they have to be replaced and the entanglement can come apart. Not sure of the specifics, but it would make things challenging. Still, that’s an Ancients Ansible in its baby form.
 
Teleportation, one photon at a time:

This breakthrough demonstrates quantum teleportation, a process where the state of a particle (like a photon) is transferred to another distant particle without the initial particle moving physically.
 
The article doesn't mention how long it took between sending and receiving, so Sig could be right.
It's not really a matter of sending and receiving. It's more that you can't interpret what the matched spin means because the spin is not something that can be controlled. It's random. If you check one end, you find that both are spinning up. As no one could know that in advance, it means nothing.
 
Or as wikipedia puts it:
"quantum teleportation only transfers quantum information. The sender does not have to know the particular quantum state being transferred. Moreover, the location of the recipient can be unknown, but to complete the quantum teleportation, classical information needs to be sent from sender to receiver. Because classical information needs to be sent, quantum teleportation cannot occur faster than the speed of light."

I was not aware that "information" was something governed by the speed of light. All of the ways that We are aware to "send" the data, so far, have that restriction, but the "information" has no speed limit.
