Well, you can also take two quantum particles and entangle them, so that these very same quantum properties are linked between the two entangled particles. You can create your pair of entangled particles at a particular location in space and time. For one, we don't truly understand quantum gravity at all, and anything we can say about it is extraordinarily provisional. For another, replacing the non-local behavior of quantum mechanics with the non-local behavior of quantum gravity is arguably making the problem worse, not better. Find out where we are in the quest for quantum gravity, and what promises it may (or may not) have for revolutionizing one of the greatest counterintuitive mysteries about the quantum nature of reality!
