Abstract
The classical understanding of gravity yields specific observ- able consequences, the most striking of which is the emergence of a 1/r2 force. In so far as communication can arise via such interactions between distant particles, we can ask what would be expected for a theory of gravity that only allows classical communication. Many heuristic suggestions for gravity-induced decoherence have this restriction implicitly or explic- itly in their construction. Here we show that communication via a 1/r interaction potential has a minimum noise induced in the system when the communication cannot convey quantum information. This provides a tight constraint from anthropic grounds on any theory of gravity that does not allow quantum communication.Citation
