This does NOT imply FTL communication. The actual key is arbitrary/random, so no information is transferred. However, both can read the same particle state. So

This does NOT imply FTL communication. The actual key is arbitrary/random, so no information is transferred. However, both can read the same particle state. So it's more like they sent the particles to each other (or from the center), "caching" whatever value is there in two separate locations. However, you don't know when the entanglement is broken, so you STILL can't communicate FTL.
