Quantum entanglement and what Einstein called "Spooky action at a distance" is real. But its not what people think of as "teleportation".
The real part is that if two particles remain in a state of quantum entanglement, then however far apart they are the act of observing one immediately affects both of them. The speed of light is no obstacle.
This article I think is rather confused and misleading, or at best not clear. I would recommend anyone curious about the weirdness of Quatum Physics that doesn't yet know much about it to watch this first:
I agree with you.
This is a big deal though, because changed states between multiple galaxies distant would happen simultaneously.
It would seem not terribly hard to devise a telecommunications device to communicate instantly rather than limited to the speed of light.
Imagine an series of clocks on earth calibrated using paired photons.
Wow...
Subs at depth all over the planet in pure sync.
Quantum communication not only instantaneous at any distance but is also unhackable?
