Have you read Rovelli’s work? As I understand it, Relatonal QM essentially says that there is no “FTL”’communication, because any effect of entanglement involves all of the “participants” exchanging information, and until they have done so, using sublimal communications, the entanglement is not resolved. I’m using quotes to denote that participants are just the things involved, not necessarily people/observers.
