Interesting. Yesterday I came across Greg Egan's hard science fiction novel "Schild's Ladder" (after reading about authors that inspired the story of the swedish game "SOMA"). The main plot is about loop quantum gravity theory (LQG). Egan uses the word quantum graph theory and it seems LQG uses the notion from graph theory.
