It can, under certain conditions, contain information about things at a distance, but a function is not a physical entity and its reduction is not a physical process, so none of this reflects anything superluminal actually going on in physical reality.
They don’t “communicate” faster than light, the wave function itself is non-local and collapses non-locally.
