The single novel (to me) idea I pulled out of that is the idea that distance is the inverse of entanglement. So the hamming distance between states would also be the real world distance (in effect) That's a very interesting theory, that could go places. (No pun intended) If this theory is correct, you might be able to modify spacetime within a superconducting container, as at least some of the electrons in them are in superposition. It's a small mass fraction, but could be a starting point. It true, there could be some basis to the plot of the movie Primer. Also, Dimensional Engineering? Maybe you could shove an aircraft sized structure inside something the size of a phone booth... ;-)
