I'm not exactly sure what you're saying. I know you can have gravitons without "quantum gravity" (as incomplete theories). I'm responding to a commenter on applications. In a global position finding system, gravitational effects could be used, as could be quantum effects. Maybe even both in the same system. It seems really doubtful to me a practical system would depend on anything graviton related.
