Ok. But they are doing it over a 1km fiber optic cable. Which is relatively close to the speed of light if you use it as intended. So I remain confused :)

Separating the entangled states or creating entanglement over that distance requires a time longer than the distance / speed of light. So whatever information that went from point A to point B did not break the speed of light barrier.
