In general, an entire spacetime … can only be seen by an observer either in the infinite future or outside the universe. This is unphysical, so …
[W]e will work with a microscopic theory that is a pre-spacetime quantum theory. … A quantum information processor which can be used as a pre-spacetime theory.
[I]t may be possible to have an underlying (“micro”) time without running into the observationally excluded preferred frame.
