> Our current understanding of physics says that nothing can travel faster than the speed of light, and yet, with quantum teleportation, information appears to break that speed limit.
The word “information” could be interpreted to mean communication faster than the speed of light, which is important to note is not made possible by entanglement.
Entanglement can’t be used for faster-than-light communication because although observing the spin of particle A affects the spin observed for particle B, the spin you observe is effectively random, so there’s no way to know that the results match up unless you compare them with another means of communication, one that is at most the speed of light.
