I'm curious; what do physicists think of the use of quantum information theory as a tool that could shed light on quantum gravity? See Patrick Hayden[1] for one person trying this. He told me that his work using quantum information doesn't require string theory. [1] https://web.stanford.edu/~phayden/ https://web.stanford.edu/~phayden/
